Instead it would just step over it and return.

I assume that this is a bug of the emulator.

No, that's authentic HP behaviour. ;-)

Indeed there are calculators where SST at a subroutine call executes that routine as a whole. This may have advantages sometimes, on other occasions it requires an immediate [R/S] to continue step by step. The HP67 and 97 behave the same way.

It looks like this is one of the many cases where HP deliberately changed the behaviour of their calculators – consistency obviously what not the most important design goal.
