Adding HighlightRange to the selection

[Reinmar]

My understanding is that since HighlightRange inherits from Range, it can be passed to Selection#addRange().

According to https://www.w3.org/TR/selection-api/#dom-selection-addrange that range is passed there by a reference and it should be updated once the selection changes.

Does it mean that someone can add a highlight range to the selection? And, if so, could it cause some problems?

Also, we could imagine that the selection is highlighting its ranges internally (so ::selection ~== ::highlight(selection)). I wonder if this could have some interesting implications.
