Add shading for context menus in Dark and Light theme

[gork7777]

Issue Details

There doesn't seem to be any shading behind the context menus, or it is very slightly and not obvious.

Dark theme


Light theme


Proposed solution

To make the menu more visible, a slightly white shadow can be added behind it in the Dark theme and a black shadow in the Light theme.

Alternative solution

@maxikuzmin If this is not possible, you can make the background color of the context menus more grey like in the search bar I guess.
