Visualization legend tooltip - remove animation #11910
Visualization legend tooltips are implemented via the angular-bootstrap tooltip Attribute directive. The tooltip fades in and out by default. The fade-out animation causes problems because the legend items are so closely placed together. When moving the mouse down to the next legend item, the mouseenter and mouseleave events get messed up by trigging on the fading-out tooltip instead of the next legend item. Setting the animation to false removes the possibility of unintentional mouseenter and mouseleave events. This makes the UI feel snappier and more consistent since the chart tooltips do not have any animation as well.
