Better error message for missing LngLat data

[nickforddev]

mapbox-gl-js version: 1.6.2

Steps to Trigger Behavior

1. Try to bind a popup to a marker using .setPopup, before .setLngLat, which is not necessarily counterintuitive

const popup = new mapboxgl.Popup()
  .setDOM('<h1>Hello World!</h1>')

const marker = new mapboxgl.Marker()
  .setLngLat([lng, lat])
  .setPopup(popup)
  .addTo(this.map)

Expected Behavior

An error saying that LngLatLike argument is missing altogether?

Actual Behavior

"Error: `LngLatLike` argument must be specified as a LngLat instance, an object {lng: <lng>, lat: <lat>}, or an array of [<lng>, <lat>]"

I'm not able to replicate the issue. After correcting your example code (setDOM → setHTML), I don't get any errors:

Can you provide a self-contained example on jsbin that shows the error?

[nickforddev]

Oh man, apologies for the typo and also for providing code that doesn't throw the error haha, it was a crazy day. I probably copied my code after fixing the problem. Here's the updated JSBin:
