rangy-highlighter partial un-highlight supported? #426
Description
Unless I'm missing something, I don't see that this feature is supported in the rangy highlighter.
Example: select some text and call highlightSelection(). Then select a portion of the highlighted text and call unhighlightSelection(). What happens is it will find any highlights that intersect with what you've selected (our 1 and only highlight in this example) and then remove the whole thing.
I'm happy to submit a PR to add partial unhighlight ability, but first thought I'd see if anyone else has done this and/or if this project is still being maintained? Thanks,
