Internal JavaScript Error after selecting quoted text to remove


I was replying to an email, when I was about to delete part of the quoted reply; while I selected the text a popup menu appeared for a fraction of a second, then vanished, I was still selecting the quoted text I wanted to remove - after that I’ve got this error message where the mail is displayed.

I can’t select any thread anymore, I can’t reply to any email anymore unless I double click so a new window opens which let’s me reply.

Update: I exited Mailspring fully, and restarted - the error vanished.

To Reproduce…

I can’t.
