Steps to reproduce

When invoked from a popup, tabs.captureVisibleTab(null, {}, cb) passes the screenshot base64 encoded data to the callback.

However, if a tab is created from the popup, and the code within that new tab invokes tabs.captureVisibleTab(null, {}, cb), the callback will always return undefined, even if the parameters are specified (i.e. the currect active tab id and/or {format: 'png'} or jpeg).

The new tab could be either active or not, the result would be the same. It looks like there is some privilege issue with Web extension tabs created through the popup, which instead grants the ability to capture the screenshot.
