using 4/28 build of apprunner on Windows: 1) launch apprunner 2) launch editor from Task menu 3) insert cursor in front of the line of text starting with word "Here...." 4) hit return 5) hit the backspace key on keyboard you'll see this big cursor appear on the left hand side of text. happens only on Windows platform.

Reassiging to Simon Fraser, changing milestone to M6

As discussed, this reflects problems with the selection being set after the underlying transactions, so we're leaving it like this for now. Will fix later.

I fixed this. The caret now knows how to draw when the selection points to offsets between child nodes of a parent node; it will draw at the start of the child node pointed to by the offset.

verified on 7/8 build.
