Attribute "Only show selected" option does not work if there is a filter expression

[SrNetoChan]

The Only show select does not work if you have filter expression set beforehand.

To reproduce:

• open a app with a vector layer (attibutetable.qgs will do)
• open the attribute table
• Set a filter to hide some records
• From that list select some records
• Enable the "Only show select".

You will notice that some of the unselected records are still vidible in the table

This is very likely in SDK
