not happening, is that the annotator doesn’t reload the new annotations in
the DOM, and/or the highlights are not shown in the text.

Have you at this point changed the content in the DOM?

My thinking is that maybe it's loading from an empty search first, then
maybe if you later swap out DOM content but don't clear the store cache the
subsequent load is a noop.

Do you see an earlier search request in the network log?

search, to display or update display of highlights?

It calls `annotator.loadAnnotations` or, if that ID was loaded earlier I
think it calls `updateAnnotation` but that will not re-anchor the
annotation in the DOM.

If you're sure this worked in an earlier version and you're comfortable
building Annotator you could git bisect your way to the commit that broke
this.
