Comment 4 for bug 1745620

I sequentially type "buwei", but 'i' is loss outside the chromium inputbox.

Note that this loss issue doesn't occur in any other gtk3/qt application when typing data to their inputbox.
Beside, when I type characters into Chromium address/searching bar (also a single-line inputbox), the loss also not happen.

So I guest when chromium decorate html inputbox, and when the inputbox has position changes/style changes/etc, there might be a wrong signal from chromium to input method that makes some charactors loss outside the input method table.

See image attached.
