When I manually select several notifications, the Select All checkbox contains a minus sign icon. If I click that to un-select the notifications I just marked, it will select all notification checkboxes on the screen. I’m assuming it’s supposed to un-select all checkboxes.

Steps to reproduce:

• Go to github.com/notifications
• Select one or more notifications in the list
• Click the Minus (-) icon in the Select All checkbox
• All notifications are selected
