Screenshot of typing booster with latin-pre filter enabled.

Description of problem:

With Typing Booster enabled (configuration provided in attached screenshot),
pressing the ctrl+up_arrow key combination in a web browser (tested with both
chrome and firefox) causes the operating system to hard freeze/lock up/hang.
The problem does not occur in gnome-terminal. I haven't tested anything else.

Version-Release number of selected component (if applicable):

ibus-typing-booster-2.6.1-1.fc29.noarch

How reproducible:

Every time.

Steps to Reproduce:
1. Enable typing booster (I'm not sure what configuration is required, but all
I have enabled is the "Latin-pre" input method.

2. In Firefox's address/search bar, type "byebye", then press the
ctrl+up_arrow
key combination.

Actual results:

Hard freeze of operation system requiring a power-cycle to restore.

Expected results:

Cursor moves to beginning of line.
