Unexpected sizing/maximization of tab dragged to another monitor

A common behaviour when using multiple monitors is to grab a tab from a browser and drag it to another monitor. This acts a little weird when moving from a window with a panel to one without. If you:

1. Open an application with tabbed windows e.g. firefox
2. Open multiple tabs within the window
3. Have the window maximized on a monitor with the xfce panel
4. Drag a tab from the window out onto a different (but identical resolution) monitor that doesn't have an xfce panel

The window created by that tab will:

1. Show that it is maximized (icon and window menu offer "unmaximize" option)
2. Switch to being truly maximized if the unmaximize option is pressed
3. Have the exact dimensions that it did on the original monitor, including the gap for where the panel was

To solve this correctly, we should answer: "Should a tab pulled from a maximized window also be maximized when placed?"
