Make holding down toolbar buttons slightly less awkward on a high res touch device by increasing the threshold needed to activate a drag.
Fix bug where dragging across the original drag start 'snagged' while the threshold was reactivated.
Bug fix: create link dialog slightly too wide.
Add some validation to the create link dialog. Currently there's no indication to the user that validation has failed other than the fact that the dialog remains in place. Adding an alert screwed up the focus on iOS.
Fixes toolbar display bug on FireFox. Not in a clean way unfortunately...
Fixes minor issue where an information modal being scrolled could scroll the document being edited. Not a fix on iOS7.
Should help to reduce unwanted side effects in the main document when some plugins are active... at least on some platforms.
Update comment.
Only add selection change listener if there isn't one in place already. In theory this ought never to happen but it still does on occasion.
