Some tiles don't load if quickly panning after zooming
How to reproduce
- Load the GoogleMutant demo and zoom in a few times.
- Zoom-in or zoom-out.
- As soon as the zoom transition finishes and you are able to pan, start panning the map in a very large circle.
- If you started panning soon enough and kept the map moving, then a bunch of not loading tiles will be shown.
Minimal example reproducing the issue
Here is a Plunkr that tries to follow the steps to reproduce the issue, although it usually only works on Chrome. Click the button under the map to start. If it doesn't occur, click the button to try again. If you successfully get a tile that doesn't load, then pan to see the bottom-right and there should be more tiles like it.
This is a similar issue to #27 (closed), although that bug was caused by the EdgeBuffer plugin and was supposed to be fixed. This issue occurs on Chrome 69.0.3497.92 and Firefox 62.0 on Ubuntu 18.04.1. Let me know if you want more information.
