Describe the bug From 7/2 I find that the typesetting of formula is gone, the newline symbol is not work, like "\\" and "\newline". I have ask some friend and try on different PC but got the same result. I'm not sure this is bug or I miss some environment setting, while there was no problem before 7/2. (I noticed it on 7/2. not sure if it happened earlier) Today I remember that drawio have desktop version, so I download and try it. and I find that desktop does not have this problem. My browser is chrome 103.0.5060.134

To Reproduce Steps to reproduce the behavior:

1. enable mathematical typesetting by extras->mathematical typesetting in upper toolbar
2. type something with newline like fig, left is preview and right is text.
3. See error

Expected behavior newline should work
