Tooltip running digest when it trigger mouseleave even tooltip-enable attribute is false.

[lg314]

Mouseenter event should not run digest when tooltip-enable is false. I found the code triggered by mouseleave.

        function hideTooltipBind () {
          hide();
          if (!$rootScope.$$phase) {
            $rootScope.$digest();
          }
        }

I wonder whether it is necessary to run digest when the tooltip has never been opened.

The value could potentially change to true, and then the tooltip could be activated down the line - we would have to guarantee that it closes properly.

I tried to change the code like this. And it works good in my case. But it should be tested in other cases.

        function hideTooltipBind() {
            if (ttScope.isOpen) {
                hide();
                if (!$rootScope.$$phase) {
                    $rootScope.$digest();
                }
            }
            else if (ttScope.popupDelay && popupTimeout) {
                $timeout.cancel(popupTimeout);
                popupTimeout = null;
            }
        }

Can you please explain things more clearly here? Your comment seems to be talking about something completely separate from the original post.
