Problem: When the disclaimer overlay is triggered, there is no close button present within the overlay. This can cause users to click on the 'block' button on the upper right and delete the tile. We should avoid accidental blocks by adding a close button within the overlay. See attached.

Clicking anywhere outside the black overlay (or clicking the label itself again) should close the layover. If this is still insufficient, we could ad a "close" link. I'm reluctant to add another "X" icon since that would confuse the user.
