Double input with fcitx5 on chrome dev under some cases

[CnTeng]

This was happend for me in niri and cosmic.

Chrome which utilizes text-input-v3 has the issue of letters get doubly input for certain input boxes, even when no ime is in use (but no issues when the process of fcitx5 is being killed).

I can reproduce this, and here's a tldr:

When having multiple chromium / electron (e.g. multiples windows from the same electron application) window running, every character typed will be repeated in current input focus field, as many times as the number of chromium/electron instance.

These chromium flags are used:

--enable-wayland-ime --wayland-text-input-version=3
