This is… true, and has been a source of personal annoyance for 
years :-)

As it is, this bug report is a bit vague, almost a meta-bug (‘many 
packages have bugs’).  Because *many* packages have this problem, 
for different reasons.  Most instances are pretty easy to fix once 
you find out the exact problem, but there's no one-size-fits-all 
solution.

Do you have any ideas to make it more actionable?

I fixed this specific example in 
3a428dd63af0bec23861a8ed1c76665e8f424265.

Thanks for the report!
