[Bug]: too many to delete - ERROR TypeError: can't access property "deleting", this[t].get(...) is undefined

[meonkeys]

Prerequisites

• I have searched existing issues and discussions to ensure this bug hasn't been reported before
• I have read the troubleshooting section in the README
• I have tested this issue with yt-dlp directly (not just through MeTube UI) as described in the README
• I have checked that this is not a yt-dlp issue (if it is, please report it to yt-dlp repository instead)

Bug Description

I have 486 completed and 33 failed. When I click "clear completed" or "clear failed" I get an error in the JS console and nothing server-side.

ERROR TypeError: can't access property "deleting", this[t].get(...) is undefined

Workaround

select a few at a time (I tried up to ten before I got tired of clicking), then "Clear selected" works as expected

yt-dlp Direct Test Results

n/a, doesn't even hit the server

Also failed the same way in Chromium version 141.0.7390.54 (Official Build) snap (64-bit), but the error in the JS console was slightly different:
