Fix failing assert when hiding header with asset shelf available 

Old code to prevent multiple overlapping regions at the same place,
wasn't handling the combination of bit flags and the alignment enum in a
single field correctly. Newly introduced flags for the asset shelf
exposed this.

Was asserting on startup for a Pets production file
(`010_0050.anim.blend`).

Steps to reproduce:
* Replace default cube with armature object
* Enter Pose Mode (makes asset shelf available for pose libraries)
* Hide 3D View header
