Thanks for tracking this down. I never use the toolbar so never tripped this 
particular bug.  The “A” people have seen with the buttons comes from the 
addition of identifying strings beneath the icons which apparently didn’t exist 
when this code was written (before my involvement).  The “a" had been 
hard-coded in.  I’ve replaced it with something sensible for each icon in 
upstream.  Emacs used to allow multiple lines of toolbars which made these more 
useful (perhaps that’s a widget toolset issue).

Though I don’t have time to lead it, I’m amenable to helping with an ELPA 
transition if someone wants to take that on.
