UI: Support interacting with superimposed icons while editing

For example you can now start entering text in the Properties or
Outliner search, and press the 'x' while the button is still in
text-edit mode.
This way you don't have to exit text editing first, before being able to
quickly clear the string with a mouse click. So this is a small
improvement for convenience.

It also works for the eyedropper (change to picking an object while text
editing) or the '+' and '-' icons in the file saving dialog.
