ui-gmap-markers doesn't work when the number of models more than ~200

[Fruzenshtein]

When the number of models for ui-gmap-markers exceeds ~200, markers don't appear on map.

As demonstration:
http://notiz.co.uk/view-notices#/map
Here by default you will be in London location.
The number of models more than 400.
Markers are not displayed.

When we drag the map in area where the number of markers less than 200, open details of a particular model and return to the map they display well.

How to deal with this?

You need to make a small reproducible example. If you want someone to dig into your business application then you need to consider paying them.
