Note that those problems were most likely already present (and probably
still are present as well) if you have `display' properties instead of
`invisible' properties.  The reason for it is that my change did not
introduce any fundamentally new behavior but only extended a pre-existing
one (move out of `display' and `composition' properties such as images) to
more cases (do the same for `display' overlays and for invisible properties
and overlays).

The main reason for extending the code to the `invisible' property was
precisely so as to make `intangible' less often necessary since
`intangible' tends to introduce significant problems when interacting with
code not specifically written with the `intangible' property in mind.
