With Extension Manager open, you can't close Brackets (Win 8)

When you open the Extension Manager dialog, you can't close Brackets with Alt+F4 or the X in the top right. The X has a hover state, but it can't be activated. The Minimize and Restore buttons work as expected though.

This is by design on all platforms. The extension manager and other dialogs are modal dialogs, and modal dialogs, by definition, prevent other actions from occurring, such as closing the program.

If it's by design, then the X shouldn't have a hover state, because that's a confusing user experience. I'd also argue that none of the menus should be focusable/clickable because they don't actually do anything when the modal is open.
