TextMesh Pro 2019.3 display bugs when viewing the glyph table

The text is flowing into the input boxes. Doesn't seem to matter how wide/narrow I make the window. Just a standard resolution HD monitor.

Also, am I imagining things or did the name of the sprite also used to appear here as well?

 

Thank you for taking the time to report the issue.

This is already known and related to the Theme / Style changes in Unity 2019.3 where editor stuff doesn't render the same as before. Since this is related to those editor changes, the issue is being looked at by the Editor team.

I will provide an update on this as soon as I have more information.
