If a bounding box is selected and "Text" checkbox isn't checked, checking "Text" doesn't highlighted the associated `syl`

If you selected a bounding box on a folio and then hovered over the text area (on the sidebar) corresponding to that bounding box, the selection color (red) disappears.

This is probably because the logic for hovering over the text area does not consider an already selected bounding box.
