I have a map where I am displaying 10 map markers that are spread across the entire globe.

I add the map markers into a container, then zoom to a bounding box for the map markers. (I have to use "zoomTo" because it may not always be a full world map required).

Anyway, the world map seems to be centred (left to right) on the longitude cutting through Australia. All of the map markers seem to be to the left of this centre with none near America (shown on the right hand side). However, if I drag the map left to right to show America again (coming in from the left hand side) then some map markers appear that weren't shown originally. I can't show any screenshots because the site is still in development but the [random] lat,lngs that I am currently using that display this issue for me are:

39.5474334311452, -130.693925892152
50.9953824449402, 46.5544276283572

23.4267190129803, -161.560225726058

This isn't the only combination of worldwide map markers that have caused this issue so any guidance as to whether this is a bug or my own fault would be appreciated.

The markers may actually be on the map tiles images that have been loaded but they are not actually displayed on the tiles within my map div.

Thanks
