Padding for selection obeys masked items sizes, it shouldn't
Padding for selection obeys masked items sizes, it shouldn't

### Bug report
If a group contains a masked element, that is larger than the mask, the padding obeys the masked item size, instead of the mask size.

#### Expected behavior:
Masked items should always be padded to the mask size.

#### Steps to reproduce:
Mask a bigger rectangle with a smaller one.
Add padding.
Padding is calculated for the bigger masked rectangle.
If you move around the masked rectangle, you can clearly see.


Thanks
