bottom-sheet: touch-action not reverted on cleanup

[jonaszuberbuehler]

Bug

After mdBottomSheet is hidden touch-action: pan-x; is not removed from parent element (ie body) preventing vertical scrolling on mobile devices.

What is the expected behavior?

Any added touch-action should be reset to initial state.

What is the current behavior?

The added touch-action ist not removed on

material/src/core/services/gesture/gesture.js

Lines 252 to 255 in 290c72a

	onCleanup: function(element) {
	if (this.oldTouchAction) {
	element[0].style[touchActionProperty] = this.oldTouchAction;
	}

.

Which versions of AngularJS, Material, OS, and browsers are affected?

AngularJS 1.6.6, Material 1.1.7, Android, Chrome

#9179 does a little bit with the bottom-sheet cleanup, but it doesn't appear to fix this issue in the gesture.js onCleanup function.

I am able to reproduce this on https://material.angularjs.org/latest/demo/bottomSheet where it doesn't clean up the style on

<div class="demo-content bottomSheetDemo1 ng-scope" style="touch-action: pan-x;">
