>> FileChooser Open/Approve button size is shown incorrectly when no Approve button text is set in `CUSTOM_DIALOG` type. Reason being that no default Approve Button text is returned during Dialog Type Property change. Since `null` is returned as Button string the Button size is incorrectly shown. The fix here addresses the issue by adding a default Approve Button Text when no text is set explicitly in case of `CUSTOM_DIALOG` type.

Yeah, initially had thought of doing this, but to keep the default text open for future changes and to maintain the default for CUSTOM Type separately I added additional properties and members. If using the OPEN type properties is fine for CUSTOM also then can use the same I guess.
