benjhayden@, please send this to an appropriate owner.

Also, this dialog is pretty annoying because multiple of them stack on top of each other and we can't dismiss them except by manually deleting them in dev tools.

Huge +1 for making all of these trace viewer warnings dismissable.

I started adding close buttons to the info-bars: https://github.com/catapult-project/catapult/issues/3722

Is the double-handled MouseLeave causing a problem other than the warning?
If so, I'll dig in. If not, I'll add it to the backlog.

No problems other than the warning, but...

we were ending up with a half-dozen warnings stacked above each other, which doesn't leave much screen real-estate for the trace. Maybe only display a maximum of one? If there is a close button that will help, but having to close six of them will still be a bit annoying.
