(closes #4533) There are several issues here.. Here's a quick brain dump: - the requestIdleCallbacks in map.js (scheduleRedraw) seem to be causing crashiness in Firefox on fast zoom/unzoom, mousewheel, etc.. anything where the view transform changes a lot and the redraws don't catch up. (commented out, reverted back to lodash throttle) - the requestIdleCallback worker queue in idle_worker.js seems to be causing crashiness in Firefox and Chrome when exiting the walkthrough. Something about deferring the tile parsing as the user leaves the intro has a problem. It might be an infinite `while` loop, not sure. (commented out, reverted back to for loop) - the requestIdleCallback in call_when_idle.js is only used to defer tile loading in context.loadTiles() - this one seems fine, and actually has maybe the biggest benefit for improving performance.
