Tab labels in Private (or Private w- TOR) mode are brighter than the one with focus

Recalling my posts in Tabs in light mode illegible (not started by me) I am still finding this issue to be active.

In Private (or Private w- TOR) mode, the labels for the tabs without focus are brighter than the label for the tab with it.

This is hard to ignore since I have to continuously scan the tab bar to try to figure out where my ‘currently open’ tab is. It is, I concede, much more of a problem with many tabs open, but that’s what I tend to have (e.g., 16 in the current window as I compose this). .

Also, among the tabs without focus there are clear variations in brightness level. Seems odd.
