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.

What fixtures are you testing with?
I just tested with slots and all was good.
I tested using IR, IB and IG and all was good.
Using an intensity and then the CMY encoders I was able to recreate the color being released but the intensity remained because of the HTP.
Can you please confirm this is also what you are seeing?
I was doing this using HSI,
I believe this stomping behavior exists only if the bottom priority fader fixtures mix colors using HSI. Using CMY, the priority maintains.
Confirmed this using VL3500 Spots as well. Once HSI parameters are introduced, the lowest priority fader is stomped on ALL parameters, not just color
Thanks for the information, I will be getting a defect open for this.
