It feels like dark magic: When using the kotlin-notebook IDE integration plugin, it "eats " away commas and opening round brackets. That is: I type them, but they do not appear irrespective of the cell type. Is this a known problem?

I saw this in earlier versions of DataSpell

Is it your case? https://youtrack.jetbrains.com/issue/KTNB-23 I'll investigate it

Yes, it seems like. Thanks for tracking it down. Looking forward to the fix.

This is actually my bug report. Any suggestions for a work around would be appreciated. Currently, I can only enter code or markdown in a browser window and I can not use Intellij for this task.

Indeed it's an absolute showstopper. I also had to move back to the browser because of the issue.

This bug appears to be fixed in version 2022.1 EAP, 22103427.89.
