[bug] part wb shape color and transparency unwanted reset

[heda]

I think this has been reported earlier, it is a bit annoying though when using custom colours.
have not searched for earlier reports...

make a solid in part wb and then change colours on the cut.

then modify any parameter/placement in any of the children of cut,
shape colour and transparency is lost, edge and vertex colours stay...

to fix it, one can tick transparency up/down once
same with shape colour, if one selects the dialogue and ticks for example down on one colour it is fixed,
one peculiar thing is that this one tick down on the colour is not saved when clicking ok, it is somehow ignored.
shape colour can also be reset with "set colours" on the cut and click "set to default",
this only affects colour so transparency has to be done through view-properties.

this is the same on 0.18, 0.19, 0.20 on my mint box (for a model like this).
have not tested anything else

obviously shape colour is not going through the same logic as edges/vertexes related to colour in the update/recompute loop.
