Discription

I came across this problem when i am using a Chinese IME in https://codemirror.net/try/ in chrome.

When i try to type in chinese, the text/code immediately preceding the cursor gets deleted. The Chinese IME i am using is microsoft Chinese IME. The problem persists in a Chrome Incognito window, however it does not occur when i use microsoft edge.

I am using chrome 148.0.7730.2

Reproduce

1. Open https://codemirror.net/try/ in chrome
2. Use a Chinese IME (e.g.,microsoft chinese ime) and start to type in chinese right behind the English code
3. The end of English code get deleted.
   ( and if you try to type chinese in the middle of a code cell, more content get deleted)
