Changes between Version 1 and Version 2 of Ticket #31661, comment 9

v1	v2
1	1	As it turns out, IE11 replaced `selection` with `getSelection()` and so this patch doesn't really do much for that browser. See also https://msdn.microsoft.com/en-us/library/ie/bg182625%28v=vs.85%29.aspx#legacyAPIs

3		Couldn't get `createRange()` to work on it either (reading into it more it should work, so I'm not sure what I did wrong just yet), and simply passing whatever it returns causes only the opening tag to appear in the right place.

5	5	I'll fiddle with it some more when I get the chance, I wouldn't doubt that I was looking at it wrong at 5:30am. :)
