Newline characters selected in span are not displayed as being part of it

If you compare these two screenshots… One has just the date highlighted because I highlighted from the beginning to the end. The other has the date plus a little bit of whitespace afterwards because I started highlighting on the line below the date and just dragged up to select the text. Doing it that way also selected the newline character to be included in the span. Once you actually hit a hot key to mark the span, that whitespace character isn’t coloured/highlighted, so you can't see anymore that you've accidentally included some whitespace.
