extend method does not accept LngLatLike or LngLatBoundsLike obj

Line 69 in 8516027

extend(obj: LngLatLike | LngLatBoundsLike) {

extend method is described to accept LngLatLike or LngLatBoundsLike types, but implementation accepts only "instanceof LngLat", "instanceof LngLatBounds" and "isArray(obj)".

Other object-like arguments are just skipped.

Can you provide an example of what isn't working? As of v1.9.0, extend does accept LngLatLike and LngLatBoundsLike.

Hi, I'm using v1.10.1.

The code is not working:

bounds.extend({lng: 10, lat: 10});

This simple object passed as an argument is LngLatLike, so method accept it. But for implementation it's neither instanceof LngLat, nor instanceof LngLatBounds, nor Array.isArray(obj), so no extension is made after all.

I am also having the same issue.

The test-cases I posted here shows the issue quite well:

@sgolbabaei There appears to be some inconsistency with the way extend is handling *Like objects. Can you take a look at this?
