Make tooltips and popups stand out more from the background

[PulsarFX]

In the default themes tooltips and popups look the same as the main window layout.
This makes it hard to see what is inside the popup / dropdown and what is in the background.

Here hides an opened popup element:

I added this CSS to make all popup elements darker to make them distinguishable.

Can we add more darkened popup elements to the default themes?

/* make all pop up elements darker, to make them more distinguishable from the main gui */
.popup,
context-menu,
menu,
menuitem > arrow,
tooltip,
popover,
popover #bauhaus-slider,
#range-current,
.dt_bauhaus_popup
{
    background-color: shade(@tooltip_bg_color, 0.5);
}

This is what the darktable theme will look like with visible popups:

The default theme is lighter on my side, and the tooltip readable... which version of dt this is?

See:

I'm not opposed to a bit more contrast, but we must at least see the same thing.

Screenshots are from darktable theme in 4.8.1

Tooltips are visible not in all cases. Try the popup element from the first screenshot on your theme.

Still readable to me:

The change you propose has too much contrast for the gray interface (default theme):

And also for the dark theme. It is ok only for darker theme to me.
