Filenames with encoded URLs no longer save correctly in URL Encode format as of 127.0

Up to 126.0b9, files with encoded URLs in their filenames downloaded normally. As of 127 onward, however, it gets changed to _3A instead of %3A, etc. Is there a setting somewhere in config to revert this?

Example:

Supposed to be: test [sound=https%3A%2F%2Ffiles.catbox.moe%2Fe547nk.mp3].png Downloads as: test [sound=https_3A_2F_2Ffiles.catbox.moe_2Fe547nk.mp3].png

It looks that things got changed and and valid separator characters are replaced by a space invalid separator characters are replaced by an underscore. There doesn't seem to be a way to affect this.

Some changes are linking to a security bug (1891234, additional filename filter checks) that we can't inspect. See sanitizeFileName, line 3488.

Ugh, that's unfortunate. I suppose I'll have to downgrade Firefox to fix this issue.
