text-allow-overlap partially ignored for symbol layer

Nobody has claimed this yet.

**mapbox-gl-js version**: v1.12.0

**browser**: MacOS Chrome, but behavior doesn't seem to be browser-dependent.

### Steps to Trigger Behavior

1. Starting with the example at https://docs.mapbox.com/mapbox-gl-js/example/filter-markers-by-input/, modify the layer layout properties to have:
`
'icon-allow-overlap': true,
'text-allow-overlap': false,
'text-optional': true,
`
2. Zoom out so the icons + layers start to collide

### Expected Behavior

Per the options, I'd expect the icons to be allowed to overlap, but not the text. The text should disappear when it starts to overlap other text or icons.

### Actual Behavior

Some of the text is removed as expected; other text is allowed to overlap the icons. Here, the bottom-right MUSIC label is correctly removed, but BICYCLE sticks around and is drawn atop the theatre icon.


Reproduce the issue using the filter-markers-by-input example and the linked jsbin, with icon-allow-overlap true, text-allow-overlap false, and text-optional true. Zoom out until symbols collide and trace the collision behavior for the symbol layer. Done means overlapping text is consistently hidden when it collides with icons or other text while icons remain visible.
