Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.

Hey,

I have a weird issue on sentry that pop a lot, related to clear(@glimmer/runtime.js:298:1)

NotFoundError: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.

I neither achieve to reproduce nor to understand from which component it's from, therefore, I think there's a bug maybe a bug in glimmer?

The issue seems to occur on all browsers, even the last version of Chrome (97)

Here's the complete stack trace on this gist https://gist.github.com/dbendaou/ec2cdd0b6808cb0182f70a5ec0a78a51

Bumping this. This happens rarely, but when it does happen, it generates thousands of errors in quick succesesion and floods our logs.

This happens usually when a browser extension (or built-in feature) modifies app's DOM tree. The most common suspect is Google Translate but there are many extensions that pull the rug out from under frameworks' feet 😃 See e.g. the lengthy discussion on this topic at react's repo: https://github.com/facebook/react/issues/11538 (and all the related issues)

Yeah indeed, in the end, my issue was mitigated by preventing google translation to translate the page 😄 Will close the issue

I see this from time to time as well, and have yet to reproduce it when I try. It is not a very viable solution to tell users to uninstall various chrome extensions and/or not use google translate in order to not break the app.

Is it possible with a more resilient handling in clearElement?

Perhaps a try-catch? Or will that anyways disturb some other inner workings?
