when Creator and editor themes are mismatched, editor highlight colors make text disappear

I chose the Dark theme for Creator, and Inkpot editor theme. Those work well together. Then I wanted to show some code on a projector during a meeting, and switched the editor back to the Default theme. Now, highlighting text with the mouse makes it visually disappear: the highlight rectangle is white, and so is the highlighted text. See screenshot.

Restarting Creator doesn't help. But I can switch back the Creator theme to Classic and then restart, and then it's OK again. So while Creator theme and editor theme can be changed independently, it seems that some combinations are not good, because the editor highlight color doesn't come from the editor theme, or something like that. Every color within the editor pane should come from the editor theme.
