Just to set expectations, unless others get involved -- and historically this is unlikely -- stuff like this eventually gets fixed but it may take a very long while. Personally, I have no intrinsic interest here. There are tons of other things and even decompilation bugs that are more engaging that I could fix should I want to work on decompilation.
