don't have palettes expand forever horizontally if large enough to hold all cells
For tidiness, the palettes should stop expanding horizontally once they are large enough to hold all cells.
I mentioned this in #174836: Time Sig Note Grouping UI has a bunch of extra slots for beam properties, which cause minor resize artifact. So tighten up but have spun this off as a separate issue here.

I don't think this is a problem. It make sense to actually have an empty spot when you are using custom palettes. I'm not advocating an entire line to assure and empty cell, but empty cells make more sense than cutting off the palette and replacing it with background. It is also consistent with the extra cells you see at the end of the lines palette for example.
The empty slot is not what I'm talking about. There is already a boolean inside the palette to handle an empty slot. I'm talking about stuff past the (possibly) one empty slot.
Regarding the lines & repeats palette, those don't have enough space to display all on one palette, so it is fine how they are displayed. I don't see any reason to be consistent with that.
Part of the reason why I want to fix this is because I don't like the resizing glitch that happens when you extended the right hand border further right...it just looks weird to have all the palette's be resized. I can think of another way to handle that, but I think it is easier to just stop the infinite horizontal expansion.
