Dropdowns do not always open after closing them

Bug description

Over the past few weeks, I noticed that some dropdowns would not open 100% of the time I went to click on them. Today I managed to record the problem. I have no idea if the double-click logic has anything to do with it. The issue seems to happen more frequently on my android phone. I've tried running lazer on the PC in single-threaded mode, but it doesn't seem to help reproduce the problem. I also tried limiting the FPS with an external program, hoping it had something to do with the framerate, but nothing.

My general settings (also used in the videos below):

• On the Android phone, I have "single-threaded" mode and "8x refresh rate";
• On the computer, I have "multi-threaded" mode and "VSync".

Screenshots or videos

Here's the Android recording. The framerate is not the best, but this seems to be the best of my phone at the moment:

When I tried with the collections dropdown, you can hear that the menu opens and then closes immediately.

I managed to record the issue on desktop (but it seems to happen very rarely):

This sounds like the double clicking issue (https://github.com/ppy/osu-framework/pull/5268 / https://github.com/ppy/osu/issues/18838). If so, it should be resolved next release. Please reopen this if you can still reproduce after the release.

I updated to the latest version (with the double-click logic fix), but unfortunately, it still seems reproducible.

I would also like to point out that, compared to what I wrote in the original post, maybe the framerate has something to do with it. I'm not 100% sure, but I just tried manually locking the FPS to a low number (with an external tool) and it seemed to happen more frequently (in single-threaded mode).

The issue happens at a specific time after the drop-down menu is closed (the low framerate helps with that).

One thing I noticed in the "transform" section of the Draw Visualiser when the problem occurs is that the menu seems to transition from a height of 0... to a height of 0 (but I don't know where else to check for more information):

I believe this is going to have something to do with focus changing logic (which also triggers a closeAll() menus).

I can reproduce quite easily with limited frame rate and mashing. Seems like it will require a framework-side fix.

Tried to reproduce this with low frame rate and both single/multi-threads, but to no avail for some odd reason...

I did try a second time and couldn't repro, so not too sure either.
