HTMLEditor Spellcheck

Is there a way to get spell checking to work inside the HTML Editor?

The built-in browser spellcheck works out of the box. You don't need to do anything.

if only. Doesn't show up in my browser (Chrome or FF).

I've shown a screen recording from Edge. Here is one from Chrome (used the online demo)

Make sure spell checking is enabled from the browser options.

yes both browsers have spelling enabled

Does the online demo work? The word Blazor should be highlighted in every browser I have tested with. It takes a few seconds for spell check to kick in though.

No the online demo doesn't workbut since it two browsers its smething deeper in my system. very odd
