PixelMapped Intensitys not obeying Inhibitive Master

I reported this a few years ago, and was told it was a feature, not a bug.
I re-requested it last year, and was told by HES/ETC earlier this year that it had been fixed.
I beg to differ.

Take some fixtures, put them in a plot (with a pixelmap layer), apply the plot to their intensity and color, and play a movie on the pixel-map layer.
Store that as a cue and execute it.
If you now put the same fixture group on an Inhibitive Master, then pull the mater to zero... it has no impact on the PixelMapped Intensity.
Knock-out the Pixelmapped intensity from the original cue, and put them at 100% (but pixelmap still controls color).. update...
and the Inhibitive Master works perfectly.

I deleted the Pixel-Map layers from my show... then added the latest PixelMap Layer Fixtures... still doesn't work correctly.

What am I doing wrong? or is this still an unfixed bug?
