Tooltip fails when closing on an element that's removed

[WilcoFiers]

I'm using the tooltip on a delete button, which delete a row in a table. The button has a mouse enter/leave effect. When I click the button, which is then deleted with an animation, the following error is logged:
Uncaught TypeError: Cannot read property 'isOpen' of null

The following seems to fix the problem:
function toggleTooltipBind () {
if (!ttScope) return; // Check that the element still exists.
if ( ! ttScope.isOpen ) {
showTooltipBind();
} else {
hideTooltipBind();
}
}

Closing this issue as potentially old, and due to lack of reproduction.

Feel free to open a new issue if you are able to reproduce this on Plunker.

I can reproduce this with a plunkr!

my fix is just "if (!ttScope) return;" as first line of hide() function

That's a reasonable & simple fix - would you like to file a PR with it? If not, I can do so, but you should get the credit :) .
