it looks like we're asking a lot of the DOM to add/remove a bunch of these markers if there are 100+ markers. I think we could be better in two ways:

1. draw the markers that are visible - we do this for column breakpoints
2. remove/add markers in the same operation.

I'm going to move it to a P3 as it is not a priority at the moment.
