Title: Tooltip Fix #2378 & #1821

Issue #2378 tooltip delay not correctly calculated
Issue #1821 Don't show tooltip/popover if leave event occurs before delay expires

Behaviour is now as follows:

* Enter - if tooltip is not displayed start show timeout
* Enter - if tooltip is displayed cancel hide callback
* Leave - if tooltip is not displayed cancel show callback
* Leave - if tooltip is displayed start hide timeout
