If an element isContentEditable, do not ignoreScrollStart incase users
are using contenteditable elements to scroll. This may have originally
been put in because it disabled text selection, and moving the text
cursor on touch. But this doesn’t seem to be the case anymore, so it
may have been put in for platform versions we no longer support. Also
fix the data-prevent-scroll dataset attribute. Closes#2091
The gestures which were being added to side menu content were also
adding the `disable-user-behavior` class, which disabled
contenteditable elements. Now passing in the gesture option
stop_browser_behavior=false, along with adding the options param to the
gestures service. Fixes#421
When a list was within a side menu it could scroll up and down, but if
the user happened to drag a little bit on the X axis, then it would try
to open the side menu and the Y scroll of the content stopped. Closes
#1541
The `tapContainingElement` method was not working correctly to climb up
the DOM of a clicked element to potentially find an ancestor label
element. Closes#1643
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.
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
