The problem
This PR is trying to fix the issue of IME in quill editor: slab/quill#4449
We found that if we want to fix the collaborative editing issue, we need to disable
batchStartandbatchEndin the handlers.https://github.com/slab/quill/blob/b213e1073bac1478649f26e3c0dad50ad0eb2a49/packages/quill/src/core/composition.ts#L42
Afterward, we found that the first letter from the IME input remains when typing on an empty line.
This PR fixes this issue.
Root cause
We found that this is caused by Quill re-inserting the child element into the parent, even when the element is already in the correct position, which causes the browser to cancel the composition.
The solution
Looking at the diff code, I’m not sure why it was written that way originally. However, it seems there is an issue with the logic, and I have made corrections here. After the correction, the above-mentioned issue is resolved
