With the move to evaluating collision boxes on the main-thread ,we missed one case where symbols with text-variable-anchor was still using the box sizing for text determined at layout time.
This was causing collision boxes to start off correct but then drift at fractional zoom levels.

gl.js.v2.2.mov

This PR fixes it by evaluating the box sizing on the main thread.
