[Bug 72734] Properties dialog should close on Return

[Kristoffer Lundén]

Public bug reported:

Use case:

When using the keyboard to view or change properties, the dialog should
be closed when hitting return. The Close button is highlighted by
default, which makes it look like it should be activated when pressing
return.

This would make especially editing properties much more convenient.
