Call stack size exceeded when calling setPaintProperty in a loop

[rychoo2]

Hello,

I am trying to imitate line animation updating line-dasharray property with a setInterval.
Here is the jsfiddle with animation step intentionally set to 1ms to speed up the error to occur:

The problem is that after several minutes of running, the mapbox crashes with error:

 mapbox-gl.js:307 Uncaught RangeError: Maximum call stack size exceeded

mapbox-gl-js version:0.39.1

Steps to Trigger Behavior

1. Open JS Fiddle above
2. Wait for ~10-15 mins
3. See console log

Expected Behavior

Animation continues to run

Actual Behavior

Animation stops, mapbox GL crashes.

Actually, for some reason I am not getting this error anymore. Anyone was able to reproduce the issue?
Could have been some temporary problem with my browser.

It's definitely a bug, and can be reproduced by running the dancing buildings example for a while.

Ok, I can confirm I got this error again a few more times. But it seems intermittent.

As a workaround I added line-dasharray-transition property to set delay and duration to 0:

"line-dasharray-transition": {
"duration": 0,
"delay": 0
}

This is likely to have been fixed in #5682 or subsequent refactors, so let's close for now and reopen if there's an evidence of a similar error occurring again.
