Too many active WebGL contexts. Oldest context will be lost.

• We have a feature that pops a google streetview (which apparently creates a new webgl context) in a modal on mapbox click. On the 16th click, the map goes blank. console reads "Too many active WebGL contexts. Oldest context will be lost."

• Behavior on Firefox: generates a warning on 16th click, but map continues to display correctly.

• Edge browsers on PC also does not experience this problem.

mapbox-gl-js version: api.mapbox.com/mapbox-gl-js/plugins/mapbox-gl-language/v0.10.0/mapbox-gl-language.js

browser: Chrome MacOS 70

Steps to Trigger Behavior

1. click on mapbox 16 times to trigger rendering a google streeview each time.
2. map goes blank

Expected Behavior

map is visible

Actual Behavior

map is blank

Unfortunately there's nothing we can do on GL JS side to fix this problem — it's a browser limitation. You'll have to fix it on the application side, e.g. by reusing the same (hidden) streetview.
