Bug 192640 – Make HTMLConverter work across shadow boundaries

• Component: HTML Editing
• Status: RESOLVED FIXED

[Ryosuke Niwa]

We should make HTMLConverter produce a valid attributed string for a selection which crosses shadow boundaries.
Right now, this doesn't work and as a result, you can't copy & paste content across shadow boundaries from Safari to Notes, TextEdit, etc...

Mac OS Sierra needs its own expected results :(

Oops, supposed to be container. Fixed.
