The issue is when you hover over an element with a tooltip and then move your mouse to hover over another element, that is positioned closely above the first, that also has a tooltip; the directive does not clear the hover state from the originally hovered element.
At the time of writing this, it is only happening in Safari. 9.x (OSX 10.11.2)
Starting from the bottom of the lists in the plunker, move your mouse up and down them, over the "action" links. Notice that the background sometimes does not change to the correct color.
I'm not seeing this on 9.0.3...what version is your Safari? My OS X is 10.11.3.
I see this with Safari 8.0.8 (I should probably update!) and OSX 10.10.5 (again I should update).
Just wanted to post the info.
I am using 9.0.3 on OS 10.11.3. I can make a screencast if needed.
Can you try this with a tooltip-popup-delay="250"? The default is 0 and can be overridden $uibTooltipProvider. We may want to consider setting the default to something higher than 0.
I think I misunderstood the original issue when I first looked at this - this is certainly a bug, but a very strange one.
I'm not sure how much we can do about this - this looks like a bug in Safari itself.
@wesleycho yeah. I did try changing the tooltip-popup-delay to no avail. I am sorry, I forgot to post the results here (that was quite some time ago).
Not a problem - unfortunately, I don't think there is anything we can do, as this looks like it is browser specific in a way that has no easy resolution.
I think the best we can do is to add a note in the Known Issues section of the documentation for the tooltip.
