p-table/Aura: Dark Mode header for Frozen + Sorted Column is transparent

[allout58]

Describe the bug

When using the Aura theme in Dark Mode (not Light Mode), a frozen column, when sorted, has a translucent background for it's header and as such allows the column headers to the right to completely clobber the text of the header.

Bad (some clipping):

Worst case (completely unreadable):
