"Current Tab" feature doesn't work when you have multiple tabs focused in more than one window

[kjozwiak]

When you have more than one tab that's focused in multiple windows, the "Current Tab" feature doesn't work as expected and always displays the information of the initial tab that's focused.

Example:

STR:

• created an XPI using the last master branch (5b85fc1)
• once installed, open a Personal container and open facebook.com
• create a new window and open a Work container
• within that Work container, open linkedin.com
• click on the Container panel

You'll notice that the Current Tab is displaying the information from the first window where the Personal container is in focus with facebook.com opened within it.
