Tooltip destroy method never triggers hidden event when using animation

Created by: mdvorak

Affects both tooltip and popover.

In hide method, when this.$tip has class 'fade', animation is executed to hide the popover/tooltip. However event 'hidden.bs.*' is executed in complete callback, which means it is executed after the animation finished (works fine without animation). Now the catch is in destroy method, when calling this

this.hide().$element.off('.' + this.type).removeData('bs.' + this.type)

hide is called as expected, but all events are detached before animation ends. I fixed it temporarily by adding

if (this.$tip) this.$tip.removeClass('fade');

before hide, but there might be more elegant solution.
