[FilipTokarski]

📝 Provide detailed reproduction steps (if any)

This happens only in Safari with links or mentions, and there are a few cases:

First example:

1. Open localhost:8125/ckeditor5-mention/tests/manual/mention-asynchronous.html
2. Select image caption text and type '@'
3. Select one of the mentions
4. Triple click on the mention
5. Try to type after the mention

✔️ Expected result

Whole mention should be selected with no crashes

❌ Actual result

App crashes

📃 Other details

• Browser: Safari
• OS: macOS
• CKEditor version: 5
• Installed CKEditor plugins: Mention, Table

It also happens the other way round - when you triple click on link in a caption and a mention in a table.

I found some issues related to triple clicking in safari here:
#1677

and here:
#1463

but I guess this is a bit different behaviour.
