Windows 11 latest beta.
Typos will be underlined in red but right clicking them will not offer any spelling suggestions - just add word to dictionary.

Bump for attention
Thank you for reporting this, Morgan. This is a bug and the team will get that fixed.
Was there any resolution to this? I'm currently experiencing this problem as well.
We are pretty confident we found the cause and we know how to fix it. Unfortunately, it involves a larger underlying change, which are actively working on, and planning to ship in v44. Until then, we'll consider this a "known issue." I'm sorry for the inconvenience.
