Answer 1

Make your query to select the last focused Window:

chrome.tabs.query({ active: true, lastFocusedWindow: true }, function (tabs) {
  //...
});

Note: Better don't take currentWindow: true because:

The current window is the window that contains the code that is currently executing. It's important to realize that this can be different from the topmost or focused window.

Use chrome.windows.getCurrent() (or .getLastFocused(), right below it) to get the current window, then look for the active tab in the tabs property of the returned window.
