Multiple GMap plots whiting out in notebook.

[cenveoanalyst]

Hello,

I am trying to build interactive bokeh plots using overlayed Google Maps. I am hoping to have similar functionality to regular bokeh plots, being able to call them multiple times in a notebook without issue. However, for Google Maps this doesn't yet seem to be the case. Exactly the first time I call exactly the first map in the following gist the map loads and works. All other maps display first my overlaid points, then pure whiteness.

This is in Bokeh 0.12.0

In updating to 0.12.1 the same code produces the same result, but I am able to zoom in and out to have the regular map show. The overwritten dots are still not showing on the second plot. Testing with a smaller dot set produces the same result.

The JavaScript console shows:

This while running Bokeh from CDN in 0.12.1.

@cenveoanalyst awesome thanks, can you recap what actions happened in between each for later reference?

1. Loaded notebook and ran (my jupyterhub is rigged to do that automatically), first two images displayed.
2. Zoomed in (on Chrome), second image displayed, no Bokeh glyphs.
