Changes between Initial Version and Version 1 of Ticket #37013, comment 4

initial	v1
1	1	Attached a patch where the markup and styling from the "Edit post" .postbox was used to replicate the mentioned effect on :focus. Some duplicate of stylings is happening between common.js and widgets.css file with different selectors, but in order to keep the different type of elements in their own designated files seemed like the proper way to go.

	3	Also the fix aligns the arrow to the arrows below it as pre-patch there was about 2-3px offset to the right compared to all arrows below it.

3	5	I tested for the Appearance->Widget page elements only for now.
