When the navigation block uses justify right, the overlay can't be closed

[carolinan]

Description

When the navigation block has lots of content and the menu items are set to justify right, the overlay can not be closed because the menu seems to be on top of the close button.

Step-by-step reproduction instructions

1. Add a navigation block. Add lots of content or use an existing menu in the theme test data.
2. Select the toolbar option to justify items to the right.
3. Enable the overlay menu.
4. View the block on the front and open the overlay.
5. Try closing the overlay.

Note: I did not test on RTL.
