Experimental 64-bit portables don't display dark theme correctly

I didn't see any other topic about this, so I figured I'd post just in case this isn't known. There are elements in the 64-bit portables that have a light theme background with dark theme text, such as the column headers in the file explorers and the status bars in the file explorers.

I'm on Windows 10 22H2.

Oh, and I should also probably mention that using the regular 6.6 portable executables, those same elements are themed correctly. So this problem is specific to the experimental 64-bit ones.
