Indenting / unindenting block of collapsed code

I don't know if it's a bug, or a request, but i'd classify this as a bug.

I would expect that when i collapse a piece of code (in php, js, css, etc - basically in any file), and then indenting it (basically put the cursor in front of the collapsed code |{...} and press tab), that the whole collapsed block of code will be indented. Currently only the first line of a collapsed block of code is indented/unindented.
