Please describe your issue in as much detail as possible:

If the sub-menu for a context menu (Manage, Launch Options, etc...) is open and a title is opened or closed on another device (Steam Deck or PC) which are both logged into the same Steam account, the sub-menu will collapse and break the menu's styling. Closing and re-opening the context menu resolves the issue.
