I'm not sure that that's due to an improvement in Teams, it's probably more the formation of scar tissue that's offering a bit of respite. But something else might suddenly happen to rip the scab off and you'll be right back where you started.
One time I decided that I wanted to edit the dictionary used by Teams because I was tired of getting a spelling underline when I use contractions. Apparently, the dictionary didn't include contractions.
Anyway, many rabbit holes later, I found out that Teams uses an undocumented hard-coded call to the dictionary used by Google Chrome. You cannot edit the dictionary, you cannot supplement it with a custom dictionary, and you cannot modify the hard-code address or use a different dictionary. You can't even turn off this call.
And don't get me started on how Teams ignores every UI standard that other Windows programs use, and it's basically not modifiable in any way.
