Changing severity to S3 because this is TP issue in Strict mode.

Can reproduce with FF 92.0 and FF 94.0a1 (2021-09-10) (64-Bit) on Windows 10.

The problem does not appear when ublock origin is activated.

What I don't understand is when this happens and when it doesn't. For example why www.ra-micro.de is affected but www.voffice.pro isn't. Both pages have the same elements blocked by TP.

This is likely a dupe of bug 1728594, as that shims is being applied here and the buttons work for me now.
