Sticky table header is not sticky if --drupal-displace-offset-top is not defined

Was wondering if we need a test but the change is so small doubt it would be worth it, if tests would even be possible.

Committed f0dfe7d and pushed to 11.x. Thanks!

The changes of the branch didn't work for me, so I overridden the CSS value to use top: 0 instead. This is working for Drupal 10.2.4.

The code modification in commit f0dfe7d addresses the majority of our issues related to tables with sticky headers. I have attached a patch file to my comment for those who wish to apply the fix as a patch.
