Typo in wp-admin.css ".widgets-chooser li" transition

[ciantic]

In wp-admin/css/wp-admin.css (line 11209) reads followingly:

	.widgets-chooser li {
			...
			transition: background: 0.2s ease-in-out;
	}

I suspect this extra colon is typo, it should be:

	.widgets-chooser li {
			...
			transition: background 0.2s ease-in-out;
	}

However it's missing completely the browser specific syntaxes for transition, so perhaps those should be added also.

It looks like all current browsers support this without prefix. Looking at ​http://caniuse.com/#feat=css-transitions it shows that the prefix would only work on mobile browsers. Most of the desktop browsers went from not supporting to support without the prefix between.
