Marker constructor does not use range param.

I'm looking at https://github.com/atom/text-buffer/blob/ce71a43eea052d969bceca6a634bdb786591dec8/src/marker.coffee, and I find it very odd that the Marker constructor does not use the range that is passed to it. I'm currently trying to debug something with decorations where it seems my range information is lost when I create the marker via TextEditor::markBufferRange().

OK, this was not the source of my problem (my problem was missing the .region CSS class when creating a highlight decoration), but I think this issue still stands, even if it is minor.
