In FED (lacking a rulebook I cannot give an exact citation) it also specifies that the fielder was laying on the ground as if they had attempted to make the play, which says to me the intent is to protect the fielder unless it is a legitimate effort to avoid contact. If this was under FED, given what you have described, it sounds as if the jump was made to avoid contact and the fielder was on or near the ground. Is this the case? If so, there's no reason to ring up the runner.

Of course, if this is OBR and there isn't a league rule prohibiting this sort of thing, it's a moot point. No foul under OBR.
