Let jQuery UI 1.11 handle touch-action compatibility for IE Touch

[georgestephanis]

Support will be getting pulled in upstream via ​https://github.com/jquery/jquery-ui/pull/1152

Once that goes and we update our internal versions to catch it, we can safely drop our ms-touch-action and touch-action CSS overrides, as per the attached patch.

See: #22583, #26297

The upstream fixes will ship with jQuery UI v1.11

georgestephanis, do we have to update our jQuery UI CSS files now? Asking because your patch removes the lines, but the ​commit adds them.

[georgestephanis]

Yes, we'd need to ship the new jquery.ui.draggable.css and jquery.ui.sortable.css files, as well as the additions to jquery.ui.slider.css, jquery.ui.resizeable.css, and jquery.ui.selectable.css -- this ticket was more a reminder to remove our own implementations when the upstream ones get released with v1.11 (which is still pending)

I have a ping pending upstream to ascertain the timeline for jQuery 1.11. Since it's a major release, it'd need to land pretty early in beta to get enough testing — I'd say at least a month before core release. Looking more like it'll miss the boat for 3.9. I'm going to punt this; we can bring this ticket back in if 1.11 ends up being released.

[georgestephanis]

jQuery UI 1.11.1 has landed in core thanks to #29833 [29847] so this should be mergeable now.

Okay, let's use this ticket then to update our CSS copies for jQuery UI.

I don't have a device to test IE Touch. georgestephanis, can you please test this?

[ocean90]

Includes copyright banner for Draggable/Sortable CSS

[georgestephanis]

Yup, will test and confirm later tonight / tomorrow.

[ocean90]

@georgestephanis Any news on this?

[georgestephanis]

Gah, knew I forgot something. I'm adding myself a reminder in slack to do it tonight when I get home.

[georgestephanis]

Just tested and the current patch works beautifully on my SurfaceRT. The dragging is kinda laggy, but it's an underpowered tablet, it happens.

+1 to commit.

In 30343:

Sync our jQuery UI styles with jQuery UI 1.11.2 CSS.

Removes also our own implementations for touch-action compatibility for IE Touch.
