Chinese IME composition deletes preceding text in code cells on Google Chrome

[twenjun879]

Description

I came across this problem when i am using a Chinese IME in jupyter notebook in chrome.
When i try to type in chinese, the text/code immediately preceding the cursor gets deleted. However, this issue does not appear if i type in English.

The problem does not happen in Microsoft edge, as i have tried. However it persists in a Chrome Incognito window. The problem also does not happen when i use chrome for other purpose except for notebook.

i am using notebook : 7.5.5

Reproduce

1. Open jupyter notebook in chrome
2. Create a new code cell and type some random English code (e.g., print("Hello"))
3. Use a Chinese IME (e.g.,microsoft chinese ime) and start to type in chinese right behind the English code
4. 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)

Sure, i can reproduce this. The exactly same problem occurs when i try this link in chrome, but nothing goes wrong when i try microsoft edge.

Thank you for providing this.

I will report this issue to the codemirror team.
