openlayers marker's not ordered correctly in z-axis?

Question

I am using drupal openlayers and things are working well except for the marker layering which is all messed up with markers that should be behind instead overlapping those in front. See screenshot.

Any ideas on how to fix this?

edit: So apparently yOrdering is the culprit here, but how do I fix this the 'Drupal way' ?

Answer 1

So I posted this to the drupal openlayers maintainer, and yes it has been accepted as a bug. Fingers crossed it gets fixed soon.
