Doesn't look like this was intended as a security bug.

Can't reproduce Firefox 89/Nightly 93 on Windows with Microsoft Pinyin input, so probably something Linux specific?

NI'ing Masayuki since this is related to IME.

Yeah, xingwozhonghua, what's your environment? (distribution and its version, ibus or fcitx or some other one?, using Firefox coming from your package manager or download/build from Mozilla?)
