To allow select elements to change options in Firefox, the simulated
tap click should not go through when the target is an `option` element.
However, the regex was too general and also prevented
`ion-option-button` on mouseup.
Addresses #1373.
Before: if an `<a>`, `ng-click`, or `<button>` inside of a .item,
was clicked, the activator would walk up .item and activate it.
Now: If an `<a>`, `ng-click`, or `<button>` inside of a
.item is clicked, the activator will activate that element.
Additionally, CSS was added so `a.item-content.activated` would look
activated.
If a text input is located in the same area as a button which was just
tapped, which was probably because of a view transition, the text input
gets focus 300ms later. This is an issue on Android because it also
fires off a mousedown event. Resolved by remembering the touchend
target then checking if it’s different from the mousedown target.
Closes#1370
