LPS-46781

Hey @natecavanaugh,

Attached is an update for http://issues.liferay.com/browse/LPS-46781.

NOTE:  This issue is a regression bug caused by https://github.com/liferay/liferay-portal/commit/2fe582f2c83f9c8d40df775e03b2ac391ef73434.

"The root of this issue is the 'addContent' component is being destroyed before the popover hide handler is fired. In ee-6.2.x the bug does not occur because the 'addContent' component is not destroyed when the add panel is closed. My fix will explicitly call the popover.destroy method from the 'addContentPreview' destructor." - @mjbradford89 

Please let me know if you have any questions.  Thanks!
