Mask stops changing after the second change

How to reproduce with the attached workflow: SD15 Dare.json

You need a cartoon and a photo models to easily see the difference. SD15 is better for speed.

Model A — cartoon Model B — photo

Before the first run: Alpha = 0 but threshold=(0, below)

select: below threshold: 0.0 Selected: (0) Excluded: (409600)
select: below threshold: 0.0 Selected: (0) Excluded: (1280)
select: below threshold: 0.0 Selected: (0) Excluded: (1638400)
select: below threshold: 0.0 Selected: (0) Excluded: (1280)
select: below threshold: 0.0 Selected: (0) Excluded: (11520)
...

so everything is excluded and I expect to see the result as a cartoon, because ModelA is cartoon and ModelB is blocked First run — I get a cartoon image, it's expected, so it's OK

Before the second run: threshold=(0, above). Now I expect to get a photo because ModelB is photo and everything is selected

select: above threshold: 0.0 Selected: (409600) Excluded: (0)
select: above threshold: 0.0 Selected: (1280) Excluded: (0)
select: above threshold: 0.0 Selected: (1638400) Excluded: (0)
select: above threshold: 0.0 Selected: (1280) Excluded: (0)
select: above threshold: 0.0 Selected: (11520) Excluded: (0)
...

After the second run I get a photo, it's expected, so its OK

Before the third run: Again, threshold=(0, below) and I expect to get a cartoon image as it was at the first run. After the run started I see animation of working "Magnitude Masker", "Model Merger (Block/DARE)" and the same log as for the firs run but the resulting image is a photo, it's the same as for the 2nd run

In order to make the mask following new settings I need to switch ModelA to anything else, run, switch back and run again. Looks like "Merger" node doesn't get the unpatched model but works with already patched instead.
