Map `idle` event not firing since 3.4 release about mapbox-gl-js

Technically, the map is never idle when you pass repaint: true to options. Can you add more context on why you need to set that option to true? We exposed this option in v3.4, that's why it "works" in older versions (because this option has no effect).

This is a good point, indeed the repaint: true is causing the issue starting 3.4.

The repaint: true in our case comes from a long time ago, when our mapbox-gl version was 0.23.0. It seems the repaint property back then was used for something different (this PR is one of the few things I found from that time) and we probably used it to work around some issues with updating data on existing map instance.

With the new semantics, it might be safer to name the property with a distinct/unique name (debugContinuousRepaint), but our ancient leftover is probably not a strong enough trigger for this, so just a minor suggestion.

In any case, we will remove the repaint: true which is all that is needed for our case, thanks for the quick help!
