Hi,
In recent 0.9 release, I noticed that md-button ripple effect's behavior has changed.
0.9: the attached ng-click handler will be fired after the ripple animation ends
0.8: the attached ng-click handler will be fired when the ripple animation begin
Currently this behavior can only happen on IOS (Android Not Tested), desktop browser is fine.
This issue seems related to jQuery. If I remove jQuery, even in IOS, it's also fine.
The further investigation shows it seems related to click hijack. angular material will stop hijack click when jQuery is used. As a result, click delay will happen. It might not be directly related to ripple effect.
Looks like click delay is a hard problem. fastclick (https://github.com/ftlabs/fastclick) is most popular library to solve this problem across different kinds of touch devices.
Maybe it doesn't make sense that angular material will repeat these efforts.
In my testing, this only happens when jQuery is loaded before Angular & Angular Material. When loaded afterward, the 300ms delay is gone and things appear to function as normal.
