chore: Properly ignore supposedly ignored errors

[Dschoordsch]

Description

Fixes #10567
new Promise().catch() is implicitly passing undefined to the rejection handler and thus the error is not caught, but bubbles up.

Demo

[If possible, please include a screenshot or gif/video, it'll make it easier for reviewers to understand the scope of the changes and how the change is supposed to work. If you're introducing something new or changing the existing patterns, please share a Loom and explain what decisions you've made and under what circumstances]

Testing scenarios

[Please list all the testing scenarios a reviewer has to check before approving the PR]

• Scenario A

  • Step 1
  • Step 2...

• Scenario B

  • Step 1
  • Step 2....

Final checklist

• I checked the code review guidelines
• I have added Metrics Representative as reviewer(s) if my PR invovles metrics/data/analytics related changes
• I have performed a self-review of my code, the same way I'd do it for any other team member
• I have tested all cases I listed in the testing scenarios and I haven't found any issues or regressions
• Whenever I took a non-obvious choice I added a comment explaining why I did it this way
• I added the label Skip Maintainer Review Indicating the PR only requires reviewer review and can be merged right after it's approved if the PR introduces only minor changes, does not contain any architectural changes or does not introduce any new patterns and I think one review is sufficient'
• PR title is human readable and could be used in changelog
