Bug: Changing Pages Stomps 'Persist on Overide'

Full Boar 4, v2.1.1 b556

Came across this behavior:

Page 1:

Master 10 List 1/1 Intensity and Color in Cue (SHOW LOOK)
HTP and 'Persist on Override' options selected
Priority 0
Master UP

Master 4 List 4/1 Intensity and Color in Cue (VIDEO LOOK Overide)
Fader - IPCB crossfade
Priority 20
Master Up (so now this is active with master 10 persisting in background)


CHANGE PAGE to Page 2. (Blank)

Don't do anything.

CHANGE PAGE back Page 1.

Bring down Master 4
Master 10 has been stomped.
Same with both User Pref Page Change Options "Leave in Background', and 'Holdover if Active'

Priorities Maintain as expected if Fader 4 is not up on Page Changes.
