Rotation causes some labels to collide

[1ec5]

I’m seeing a couple labels collide:

As soon as I change styles, that overlapping “N 4th St” label disappears, and it stays hidden if I change back to the original style (Mapbox Streets):

But if I gingerly rotate the map, the “N 4th St” label reappears, and resetting the rotation doesn’t fix the collision.

This is with the changes for #1666. Doesn’t reproduce in mapbox-gl-js.

Reopening this with some new examples of collisions I've noticed from MapMode::Still renders with a rotation applied. I suspect these are old bugs we just never caught, not recent regressions.

Collision between Valley Stream, Hempstead and a route marker

Collision between Point Reyes National Seashore and a route marker, San Francisco and Oakland labels appear to collide as well

@mikemorris what is the code / setup for reproducing these? can you render the images with collision boxes?

@mikemorris thinks #1689 (comment) is a bug in the project that uses mapbox-gl-native.
