ColumnControls dropdowns scroll off-screen with FixedHeader

Description of problem: When a dropdown menu is enabled with ColumnControls, one of the following will happen:

• If the real column headers are still in the viewport, then the dropdown menu displays correctly.
  
  • If the user then begins scrolling downwards, the dropdown menu will then scroll offscreen as the FixedHeader transitions in.
• If the real column headers are outside of the viewport and FixedHeader is active, the dropdown menu button (hamburger icon) can be clicked, but the dropdown menu will render outside of the viewport.
  
  • If the user then scrolls upwards back to the real column headers, then the dropdown menu will scroll into view.

Tested in Firefox ESR 128.11.0 and Safari 18.5 (20621.2.5.11.8).

Thank you! I should get a fix for that in tomorrow.

I've just made various commits (1 and 2, along with a few others) to address this issue.

I'll be doing a release of FixedHeader 4.1 and ColumnControl 1.0.4 soon to address this problem.

Thanks for letting me know about it.

Hi Allan - thank you! It seems the GitHub repository you have linked may be private however since it is returning a 404 for me.

Oops! Forgot to make it public after the release. That's it done .
