The branch, workspace, and environment controls sit in a fixed-width strip,
so a larger interface font pushes their labels into each other. The strip is
now a query container and the labels hide below a rem-based threshold -
rem scales with the interface size, so the controls fall back to their icons
exactly when the text would start to overlap, at any font size or window
width.
