• Version 95.2.0

additional notes

• I Tried Chrome too, Chrome seems to be working fine, so this looks to be a problem only with Firefox
• Desktop works fine with Firefox, don't see this issue there.
• If I use the / command and select a header, this issue does not happen. Seems to only be a problem if I'm typing directly.
