Typing in Japanese in Helix Within a Zellij Session Doesn't Render Properly

[tahoeschrader]

Summary

When typing in Japanese (within a Zellij Session only) the text does not render as you type it. Instead, it oddly renders off to the right side (see attached video). This does not happen when repeating the same steps with Vim.

• Typing in Japanese in the terminal renders properly as you type it
• Typing in Japanese in helix renders properly as you type it
• Opening a Zellij window and typing in the terminal renders properly as you type it
• Opening a Zellij window and then helix and then typing does NOT render properly as you type it
• Opening a Zellij window and then vim and then typing does render properly as you type it

Was able to reproduce this bug in both Wezterm and Terminal.app (default Mac terminal).

Zellij version is 0.41.2
Other versions listed in bug report.

Reproduction Steps

I tried this:

1. Open wezterm manually from mac launchpad
2. zellij
3. hx test.txt
4. press i to go into insert mode
5. change keyboard from English input to Japanese input
6. type arigato

I expected this to happen: see kana/kanji as you type at the location of the cursor.

Instead, this happened: kana/kanji only renders at cursor when you press enter and instead is shown partially rendering far to the right of the window
