Z-index bug with filters

[jwhear]

What: the filter dropdowns render behind the cards. In this screenshot I have the "Status" dropdown open but it's largely obscured:

Steps to reproduce:

• Go to a particular board
• Use search ("k")
• While search results are up, click "Filter these cards". The filters will open beneath the search results.
• Close the search results and exit search mode
• Try to use the filters on the board--the dropdowns will be rendered beneath the cards

Environment:

• Brave 1.84.141 (Official Build) (64-bit)
• Chromium: 142.0.7444.176
• Linux (Omarchy 3.2)
