hl-line seems to leave its overlay's priority unspecified (good!), which
means that it should take precedence over overlays which are larger
(e.g. span multiple lines) while smaller overlays within the current
line should take precedence over it.

Can you describe your particular case?  What are the overlays that
"disappear", what do they cover, and why do you think they should not
"disappear" like that?

I must admit to disliking explicit overlay priorities, which tend to
just lead to more problems down the road (needing to specify priorities
on more overlays, which in turn cause yet more problems, ...), so if at
all possible, I'd rather avoid doing that.
