// There are several cases where text isn't visible/presented to the user but

// offering scrolls to these sections as its confusing (in fact, document
// Markers will avoid creating a highlight for these, despite the fact we can
// scroll to it). We probably want to do this for general SharedHighlights as
// well but that will require some more thought and spec changes but we can
// experiment with this for TextFinder to see how it works.
