Top Bar Header inconsistent styling, alignment, weird boxes

When the top bar header appears, so do these weird little boxes that I presume are related to the static table header.

Since Spotify's update, I'm not sure what is intended for the Play button in the header is to look like as Fluent.

Edit: The two rectangles highlighted on the side have since been fixed and merged in master. The alignment of the text at the top is still off. However, it seems to be another problem relating to line height relative to the font-size changes, that will need a separate fix.

The Play button used to be in Fluent style but it was broken as I remember
