I don't know about this. To me it seems counter-intuitive. How can an
item be "selected" if it is hidden? The user can't select an item that
they didn't see.
To me, if filter rule was applied the developer should be
de-selecting all the items anyway, to force the user to validate the
User is looking at a list of all files
They select some to copy to the clipboard, paste in another window
The user applies a filter (*.jpg)
They sholt shift and click the bottom element to select all, they
In this case if the selected items are not de-selected when they are
hidden, they will get deleted along with the JPG images, which is
surely not what the user wanted.
In fact, I cannot really think of a case where it would be usefull to
the user to maintain selections across applying filter rules. After
applying any filter, the user would surely only expect any operations
they perform to be acting on what they *see*, and nothing more.
So really, in what situation would this API be usefull at al? To me it
looks like a simple oversight.
