Extension crash when tagging TiddlyWiki homepage

[MAX10541]

• Can you describe the problem and bug in more detail?

     The extension crashes when I try tagging TiddlyWiki home page.

• How can we replicate the issue?

1. Open https://tiddlywiki.com/ .
2. Try to add tags.
3. The extension will freeze for a few seconds, then crash, restart, and no tags will be added.

• Expected behavior (i.e. solution)

     To be able to tag the page correctly.

• Error stack (from extension crash page)

     Not sure how to get this (sorry!).
