[bug] IME window position appears out of input/textarea (cannot inline-input) on Tauri v2 apps in Linux

[sksthrs]

Describe the bug

Typing in input or textarea with Japanese IME enabled, IME window appears out of the input/textarea.
This is different from #8264 or #5986

• This issue appears only Tauri v2 apps (v1 apps do not have this issue)
• IME window in this issue has both typing area and candidate selection (in previous issues, candidates selection is out of elements)

Screenshot below. IME window (typed "せかい") is placed far right-bottom of app window, overlaying on month display of the screen.

Additional information:

• IMEs : Fcitx/Mozc and iBus/Mozc (Mozc is open-source version of Google Japanese IME)
• OS : tested on Linux Mint 21 (based on Ubuntu 22.04) and 22 (based on Ubuntu 24.04)

Reproduction

npm create tauri-app@latest
(choosing npm/Vanilla/TypeScript)
cd (projectname)
npm i
npm run tauri dev

type in input element with Japanese IME enabled

Expected behavior

typed letters are shown in input element
