#2278: test that the Properties flip buttons keep the reference app's names

The Properties panel's flip buttons had been renamed Flip Horizontal and Flip Vertical, which are the Transform panel menu's names. The test lays out the Transform section for a selected rectangle and reads the screen-reader names of its buttons: Flip Along Horizontal Axis and Flip Along Vertical Axis must be there and the old names must not. With the old labels the first is missing.
