Thanks for the recipe -- I can reproduce this issue, too.

We could fix this in help-fns, but I wonder whether there's something
that should be fixed on the nativecomp side -- in this case, it appears
to not set up...  something...  that allows you to find my-file.el.
I.e., `symbol-file' isn't able to find my-file.el, and it probably
should be?

I've added Andrea to the CCs; perhaps he has a comment.
