State: closed
Merged: Yes

Summary

Fixes #23998

This PR resolves a visual issue where the sticky table header in the datasets hit-testing page uses a transparent background in dark mode, causing scrolling content to show through the header and creating poor readability.

Changes:

  • Restored --color-background-section-burn in dark mode to rgb(24 24 27 / 0.6) (semi-transparent)
  • Added backdrop-filter: blur(5px) to the sticky table header for proper glass morphism effect
  • This approach maintains the modern UI design while preventing content bleeding through

The fix uses the standard pattern found throughout the codebase where backdrop-blur-[5px] is combined with semi-transparent backgrounds to create proper glass morphism effects, rather than resorting to opaque backgrounds.
