Research direction

Review the Firefox warning and the linked MDN scroll-linked-effects guidance, then inspect how FixedHeader currently provides fixed positioning. Determine whether position: sticky can replace the existing behavior across the relevant use cases; done means a clear decision to rewrite or deprecate FixedHeader, with documentation describing the chosen path.

Written by the indexing model from the issue text.

Description

When you use FixedHeader in Firefox you will see an error in the console:
"This site appears to use a scroll-linked positioning effect. This may not work well with asynchronous panning; see https://developer.mozilla.org/docs/Mozilla/Performance/ScrollLinkedEffects for further details and to join the discussion on related tools and features!"

I intend to switch my application over from using FixedHeader to using position: sticky, as recommended in the above article. Once I have done so I will post my findings here as I suspect it would be better for FixedHeader to either be rewritten making use of position: sticky, or for it to be entirely deprecated and documentation written to help people write their own fixed header CSS.
