Please give a brief summary of your issue:
Underline error in Richtext on Safari

Please describe your issue and provide steps to reproduce it:
Firstly, I insert a new freeText with Montserrat/ Noto Sans/ Oswald,…
After that, I underline to those FreeText.
Secondly, I increase fontSize greater than 25px.
Then a UI bug occurs on Safari, not Chrome.

I found the reason to be textBaseline always to be alphabetic on Context canvas. I try to set the textBaseline to be bottom but it doesn’t work. Cause Context canvas always restore, it makes textBaseline always to be alphabetic after per drawing.

Can you adjust it in CoreControls?

Please provide a link to a minimal sample where the issue is reproducible:
