comments in sub patchers appear on main canvas

[yannseznec]

Any comments that are in any subpatches (and sub-sub-patches, etc) will appear in the main patch when it is loaded by PdWebParty. this makes it pretty much impossible to use comments apart from in the main canvas.

@yannseznec That sounds like a bug. I will fix this later when I have some time.
