I'm using FF Beta (38.0) and the Tree Style Tab add-on and noticing some UI issues when toggling the Reading List sidebar.

### Steps to reproduce:
1. Install the Tree Style Tab add-on: https://addons.mozilla.org/en-US/firefox/addon/tree-style-tab/

2. Add some items to your reading list.
3. Go to a random page (like http://www.ign.com/articles/2015/04/14/gta-5-pc-review) and enter reader view.
4. Toggle the "Close Reading List" button in reader view a few times.

### Actual results:
On my machine, it seems to float the tabs awkwardly out in the DOM area.

### Expected results:
Not that.

The reading list sidebar is gone, so marking WFM.
