Hmmm… I don’t know. I saw the strange math toolbar in dark mode too. But what can be done?

One can switch the mode and the presentation is switched immediately.
I don’t think the application is able to change the icons when the switch occurs (I’m not sure).
The solution would probably be to design the icons careful for both modes.
That means to choose colors not too dark and not too bright.
