This bug is rather specific but definitely reproducible and does happen in practice.

Steps for Reproduction

GIF of this happening:

1. Use Chrome.
2. Create a new Google doc: https://docs.new
3. Type in Sentence wthi a typo. Copy the sentence.
4. Visit https://quilljs.com
5. Paste.
6. Wait for wthi to get a red underline. Then click it and accept the suggestion.

Expected behavior: The suggestion should be selected.

Actual behavior: The entire sentence is deleted. In the console:

addRange(): The given range isn't in document.
value @ selection.js:294

I got this solved by formatting the pasted content to plaintext before spell check using -

quill.clipboard.addMatcher (Node.ELEMENT_NODE, function (node, delta) {
    var plaintext = node.innerText
    var Delta = Quill.import('delta')
    return new Delta().insert(plaintext)
})

Or use - https://www.npmjs.com/package/quill-paste-smart
