While I don't have a mouse and used a trackpad, this example worked fine for me in Safari 15.3.

This looks like Chrome. Chrome uses an old version of WebKit forked in 2013.

I see a couple existing bugs about events in the presence of 3d transforms. I didn't dig deeply to see if they are different, or obsolete, or anything like that. But someone should try to reproduce this with an actual mouse with a right button before closing as a Chrome-only bug.

The video doesn't match the link to the test content. And this appears to be Chrome.

From the video it looks like the tilted content might go behind another transparent layers, so this could be correct behavior. Please re-open if this is a bug you can reproduce in Safari.
