Spellcheck Inconsistent/ Broken

[azollafox]

Expected

I would expect the default spell check on my Mac to work as I have set in my Keyboard settings in the Mac app.

Observed

The spell check will only get one of the misspelled words in a document.

Reproduced

1. Open a new or old note and create misspellings
2. Look for the right squiggles that highlight incorrectly spelled words
