Title: Fix of memory leak with Hover boxes inside HtmlContainerInt.

This commit will fix of memory leak with Hover boxes inside HtmlContainerInt.
_hoverBoxes kept links even if control was cleared

If text inside HtmlControl was changed then HtmlContainer clears. But _hoverBoxes still contains reference to elements and produces a memory leak.
