I can confirm this happens with the library list as well, regarding software/game entries. I've had success with turning off GPU acceleration for webviews - but I think this is may be a placeabo, so take the "workaround" with a grain of salt
EDIT: Just to clarify, here's some system info. I am running KDE over Wayland, to be clear!

Your system information
Please describe your issue in as much detail as possible:
Submenus such as that of "Store", "Library" and "Community" do not always disappear when they lose focus.
I am able to consistently reproduce this in my Sway desktop environment by hovering over a menu item to reveal the submenu and then switching to a different workspace.
Enabling the "Enable context menu focus compatibility mode" option in the settings does not resolve the issue.
The submenus seem to only disappear when you return to a steam window.
Here is a video of me reproducing the bug:
