`symbol-z-elevate` does not work when `text-pitch-alignment` is `map`

[Ádám Barancsuk]

mapbox-gl-js version: 5.3.0-beta.1

browser: Chrome

Steps to Trigger Behavior

1. Add a fill-extrusion layer
2. Add a symbol layer on top
3. Set symbol-z-elevate to true on the symbol layer
4. Set text-pitch-alignment to map on the symbol layer
5. Observe symbols stay clamped to the ground even when on top of fill extrusions.

Link to Demonstration

I'll provide a demonstration if needed for reproduction.

Expected Behavior

Symbols are draped onto the top side of fill extrusions.

Actual Behavior

Symbols are draped onto the map's ground level.
