11636	Improve selection.getSelectedHTML, range.cloneContents and range.deleteContents	Piotr Jasiun		"Because of custom implementation of drag & drop (#11460) we will use  `selection.getSelectedHTML` and `range.deleteContents` more often to read and remove dragged HTML. Current implementation of `selection.getSelectedHTML` can not be based on `range.cloneContents` because it changes range (#11586) and works not as we could expected.

For this reasons we need to reimplement `selection.getSelectedHTML`, `range.cloneContents` and `range.deleteContents`.

`range.cloneContents` and `range.deleteContents` should behave more as user could expect than simple clone or delete. For example:
 - for '`xx<a href=""foo"">b[a]r</a>xx`' `range.cloneContents` should return '`<a href=""foo"">a</a>`',
 - for '`<p>[foo]</p>`' `range.deleteContents`' should remove whole paragraph,
 - for '`<table><tr>[<td>foo</td><td>b]ar</td></tr></table>`' `range.deleteContents` should change contents to the '`<table><tr><td></td><td>ar</td></tr></table>`'.

`selection.getSelectedHTML` should be based on `range.cloneContents`."	New Feature	new	Normal		General
