Showing row & column headers unreadable

This has been going on since at least 6.3.0, but maybe earlier and is still present in 6.3.2.

Selected items, particularly in UI lists that are from Libreoffice (not widget drop downs from MacOS) are shown with white text on white background, and thus unreadable. One has to move to the next or previous item in the list to see the other item's text. In Calc, this means that the font and size as well as the row and column headings are invisible since they are 'selected'. (Font and Size are also invisible in Writer) This happens in all components including in Preferences.

If a color other than Graphite is chosen as the MacOS highlight color preference, everything works as expected and is visible. It does not matter if Light or Dark mode is being used.
