"[ThumbnailGenerator] file was removed before a thumbnail could be generated, but not removed from the queue. This is probably a bug"

Initial checklist

• I understand this is a bug report and questions should be posted in the Community Forum
• I searched issues and couldn’t find anything (or linked relevant results below)

Link to runnable example

https://stackblitz.com/edit/vitejs-vite-dow9n8gt?file=src%2FApp.tsx

Steps to reproduce

I couldn't readily figure out how to install the missing npm packages on stackblitz, so my example does not compile: https://stackblitz.com/edit/vitejs-vite-dow9n8gt?file=src%2FApp.tsx

Steps to reproduce:

• Upload 25 large dimensions and filesize (20mb, 6000px by 9000px)
• Use Firefox version 135
• While uploading, rapidly click the "x" button on the thumbnails that are 99% or 100% completed upload
• The upload will become very laggy and nonresponsive
• The console message indicated in issue title will appear

Expected behavior

The uploader should cancel the images that should be cancelled, and should not emit an error console message.

Actual behavior

A console message says that there might be a bug.

I have the set of images that caused this issue, however, they are from dpreview so I do not want to post them publicly as this might be a copyright issue.
