Is there a way re-dock the floating window of 'commit side-by-side'? Follow

Generally, When I click one item on VCS commit view. It opens side-by-side view on editor tab area.
But, When I drag-out it from there. It changes to floating window.

The problem is here.
I have no clue that how to re-dock into tab.

The floating window doesn't have any tab. So that, I cannot re-dock into original place.

Is there a way re-dock the floating window into editor tab?

Best regards,
RHO.
