Closed sidebar state is not saved as expected

Adding GIF demo

I believe that this behavior was solved in 🐛 Mercury tray resizes when entity browser modal dialogs are opened Active , which is included in the latest 2.1.6 and 2.2.0-beta4 releases. We should now be tracking the current width of the sidebar and responding to that.

As I was reviewing, I noticed that I'm modifying the innerHTML of the button to toggle between "Hide sidebar" and "Show sidebar," but not doing that to the title attribute. This means that when you roll over the button the tooltip will always read "Hide sidebar." (I also seem to have a habit of somehow clicking right on that tooltip, which intercepts the click.)

Setting to Needs Work pending that title change. Let us know if you discover other scenarios where the sidebar isn't behaving as expected. Thanks!

I experienced this out in the wild today. I think it's something to do with configuration of sites that don't have the dialog tray width explicitly set. I'll test and find a solution along with the label switch.
