I think that would be an improvement. I think the best solution would
be for the face property of an overlay (and similar properties) to not
apply to the before-string, the after-string, _and_ the display
property of the overlay.
Can someone implement that? It should not be fundamentally hard;
making the properties apply is what is hard.
Note that there are additional problems. One example (which I have
already reported) is that the face of the character in the buffer
after the overlay start location (which is not even in the overlay if
the overlay is of length zero) is applied to the before-string and
display properties of the overlay.
The fix we are discussing will get rid of this problem, right?
Another example (which I think I
have not previously reported) is that the face of the character in the
buffer _after_ the overlay end location (which is _never_ in the
overlay) is applied to the after-string property.
Let's consider that after this fix is done; perhaps this will
solve that other problem as a byproduct.
