Panel view collapse/expand animation broken

[joaomoreno]

This commit broke the collapse/expand animation: d4f8481

On my mbp, I don't see the animation any more unless I continuously click the header to collapse and expand many times in a row.

@bpasero I'll figure out a better fix than d4f8481

@joaomoreno weird, that must be an issue you only see when using MBP touchpad, it does not reproduce when using a mouse on any OS.

[joaomoreno]

Yeah I figured it was platform/hardware specific...

I'll try to find a way to distinguish between initial creation and other events. 👍

[bpasero]

@joaomoreno OK, I tried that initially I think but failed to get that right because some views where coming in just a bit later with a delay.

[joaomoreno]

Hmmm this is really weird... your change actually makes a lot of sense. Investigating...

It was related to the order of listeners to that onDidChange event. We gotta add the listener sync, but we must react to it after the next animation frame. 👍
