Hi,
Please find attached patch for mentioned issue:
*Issue*: Re-docking on the main tabset is broken
*Explanation*:
We were missing 'moveable' property. It should be set to false while
creating new Browser panel. By default it is true for all registered panels.
I think both browser and dashboard panels were moveable. that is why
dockable tab couldn't determine where to re-dock.
I have also added support for moveable property in Panel class.
Please review.
Thanks,
Surinder Kumar
