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
