Nit: I wonder if we could deduplicate this long line of code that's duplicated below, but not a big deal.

Yes, but I don't have any idea, do you have?

Maybe seperate that line into something like:

function _updateDOM(){   DOM.setTransform(this._element, `${anchorTranslate[this._anchor]} translate(${this._pos.x}px, ${this._pos.y}px) ${pitch} ${rotation}`);}

If you move the pitch and location calculating code into this function, then it can live in the marker's scope.
