Causes IE & Safari to crash

[code-tree]

Including this library causes my app to crash in IE/Edge and Safari (all versions). Works fine in Firefox and Chrome. Crashes during animations, not during load.

I have reproduced to some degree, where in IE and Safari the tooltip gets frozen after a while (though doesn't crash browser in this case). Simply hover in and out of button multiple times until tooltip freezes.

I think we have the same issue. We are using Angular 2 Material and web-animations-js. Error message:

maybe related to web-animations/web-animations-next#411

Yes, now I check it, it does produce error in the console. My app just crashes so I never got to see any message 😛

Release https://github.com/web-animations/web-animations-js/releases/tag/2.2.4 has a fix for this, please let us know whether this is still an issue for you.

I'm using Safari 11.1(13605.1.33.1.2) on mac and iOS 11.3 and started getting this issue again:
Unhandled Promise Rejection: TypeError: b[d].push is not a function. (In 'b[d].push(e)', 'b[d].push' is undefined)
