autohide_sidebar.css stopped working consistently as of 147.0.1

It starts working again after restarting the browser, but after tabbing out of firefox for a longer period of time it seems to stop working afterwards. I need to click on a tab in order the sidebar to pop, but then it immediately hides, I can't describe the issue without a video I guess.

In any case I haven't had this problem since 2022-3 and back then it was because I forgot to update csshacks for many months, until I the config broke.

Does this issue still occur? Sorry I haven't replied earlier, but I had an experiment running in nightly 149 about a different issue with autohide_sidebar.css a few weeks back where I left the browser running in background for a week or so. I could not experience this kind of behavior then.

I haven't updated, I disabled it shortly after opening the issue, since it forced me to restart the browser every few hours in order to keep it working constantly.

I can enable it right now to test if you think it should be fixed, but since my workflow consists of many windows and tabs, it's a bit problematic that I need to restart the browser so often.
