Bug ID: 1382982
           Summary: Fedora iBus typing language detector breaks events
                    call stack of web pages
           Product: Fedora
           Version: 24
         Component: ibus
          Severity: urgent

Created attachment 1208438
  --> https://bugzilla.redhat.com/attachment.cgi?id=1208438&action=edit
html page for test purpose

Description of problem:
My Fedora box is configured with two typing language between which I can
switch, English and Chinese.
I'm using Firefox v49 as browser.
I'm developing a webpage, a registration form using jQuery on the validation
part.
The registration form contain 4 input controls with 2 password controls, all
validated on the blur event. The form script is kind of complex one using blur,
and focus events and a list of functions.
The form script completely mess up on the live validation of the fields due to
the presence of the two password controls on which only latin alphabet is
allowed. The ibus language detector change on the fly when the two password
fields received focus causing blur and focus events of different contols to
happen in unexpected order. It is like ibus is taking the focus and releasing.
I tested both jQuery (all the available methods) and pure javascript with the
same result.
I had the chance to try other websites using blur and focus events on password
fields and are completely mess up too.
To finish my job I will unset the Chinese IME. 
I can't guess what is about application development in the same context.

Version-Release number of selected component (if applicable):
Fedora 24 4.7.5-200.fc24.x86_64
ibus-1.5.13-3.fc24.x86_64

How reproducible:
https://jsfiddle.net/8tqwL7y5

Steps to Reproduce:
1. Settings, Region and Lanaguges, input sources: set English (US) and Chinese
(intelligent Pinyin) 
2. try the link 
3. try the webpage attached

Actual results:
Blur event doesn't happen or happen just mixed up with other events like other
control's Focus events.

Expected results:
Blur and Focus events get fired in common order on the events call stack

I tried that page with "Chinese (intelligent Pinyin)".
When the focus is out, every input box launches the alert dialog.

I think I don't see your problems.

No, on the password fields their respective blur events are fired when they
received the focus.

You should set English and Chinese languages together.

Read the alerts carefully (if helps comment out the javascript for the focus
events).

The problem happens both if you have selected the English or the Chinese IME.

I'm sorry you can't catch it.

Please note that I'm inside a Virtualbox VM. 
My Fedora 24 is the guest OS.

Who knows that this makes any difference..

I think I read your problem while I don't catch your description completely.

I don't think your problem can happen in every desktop.
Describe which desktop you tried.

Me too.

The problem is simple: on the password fields their respective blur events are
fired when they received the focus.

In theory, this means that any login form of any website that do client-side
validation on the blur events get broken (it appears a good trick to contain
the chinese people from using Linux to surf Internet)

If I unset the Chinese IME, the problem disappears. So, it seems difficult the
problem is related to the host OS.

However, to answer, I'm using Windows7 SP1 64 with KVM acceleration enabled.

No, I don't ask Windows and we don't support IBus on Windows too.
I'm asking you which desktop is used in Fedora 24 on VM box.

I verified XFDE is no problem.

--- Comment #10 from Fedora End Of Life  ---
This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '24'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 24 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

I think this is not relative with ibus.
Even if I delete "Chinese (intelligent Pinyin)", I can reproduce this problem
in both GNOME Wayland and GNOME Xorg.

I tried attached test-html3.html

@[e-mail]
Probably I think this issue is caused by jquery or firefox?

Forwarding to firefox since this can be reproduced without ibus.
