These are no longer needed as the visual highlights in PDFs are now created by SVG elements above the canvas, rather than by a background color in PDF.js's text layer. Removing these overrides fixes a cosmetic issue where overlapping text boxes in the selection layer could create different shades of blue (or whatever the selection color is) instead of blending into one, as shown in https://github.com/hypothesis/private-issues/issues/108#issuecomment-1115392598.
