Title
Browser spellcheck correction removes adjacent text when URL plugin or "enter=BR" is enabled

---

Description
When the URL plugin is included or "enter=BR" is enabled, using the browser’s native spellcheck context menu removes unrelated text that follows the corrected word.

This does not appear to happen when the URL plugin is excluded or "enter=P".

Reproduction Steps
The sandbox below demonstrates both scenarios:

Demo 1

1. Open the demo sandbox:
   https://codesandbox.io/p/sandbox/358nlp
2. In the editor, type a misspelled word such as:
   cauzing
3. Immediately after it, type another word, for example:
   test
4. Right-click cauzing
5. Use the browser context menu to correct the spelling

Demo 2

1. Open the demo sandbox:
   https://codesandbox.io/p/sandbox/358nlp
2. In the editor, right click on 'followin'
3. Right-click following
4. Use the browser context menu to correct the spelling
