Is this a bug? One-way arrow showing through area

Hi all

You may need to tell this newbie that he’s made an error somewhere in the tagging - but if not, is this a bug?

https://www.openstreetmap.org/way/649255035

The pedestrian area obscures the service road that runs underneath it (good) but the one-way arrow on the service road shows through it (bad).

This is a known bug in the rendering of the map:

Seems the developers deem it to big a performance issue to correct given the rareness of it occuring.

Thanks.
