Problem with CSS animations using Glimmer?

In this crude example, you will notice that if you hover over two of the components (in quick succession) the tool tips fade in and out nicely.

This worked fine with Ember Release and Beta (1.12.0), However, with Canary the CSS animation is triggered again (Notice the flickering)

Could anybody out there with more knowledge of Glimmer shed any insight?


Edit: Please don’t just suggest I use Liquid Fire

Turns out its a bug
