Hairpin - handle cannot be selected

When a Hairpin is in edit mode the handle that controls the height of teh hairpin cannot be selected.
Reason is that it is too close to the anchor that controls the length of the hairpin.

It becomes easier if the mag. is increased to around 250%.

It also seems that the problem may be that the displayed handle is slightly offset from the 'selection' area defined for the handle.

Anyway there is a collision problem between the two handles.

Note that issue #266369 is also related to the rendering of this handle.
