Error when switching notes

[msbentley]

After running a search I rapidly switched notes from the top two in the search (back and forth) and was met with the error below:

Error
Joplin encountered a fatal error and could not continue. To report the error, please copy the *entire content* of this page and post it on Joplin forum or GitHub.

To continue you may close the app. Alternatively, if the error persists you may try to restart in safe mode, which will temporarily disable all plugins.

Message

Steps to reproduce

Unable to reproduce yet, but I'll post back if I trigger it again

Looks like a bug in the Rich Markdown plugin content script. @CalebJohn, I think it might be that line: https://github.com/CalebJohn/joplin-rich-markdown/blob/87cfd7821b5b0e015f4c274bfed86cecc3b9a834/src/overlay.ts#L37 Perhaps "outer" is not always defined when the note has just loaded.

Thanks for identifying this @laurent22. Fortunately, I was able to reproduce this repeatedly and confirm the issue.

@msbentley I've created v0.6.2 that includes a fix for this issue. It should become available within an hour. Thanks for the report!

[msbentley]

Fantastic, thanks @CalebJohn @laurent22 for the speedy bug tracking/fixing!
