Cross pane move: viewport transfer · case 02
The tab workspace reports an incorrect viewport transfer.
Case contract
Moving a tab removes its source view and inserts it exactly once in the target pane at a clamped slot, preserving document and view state.
Why this case matters
Offline tab/panel workspace behavior; no browser or desktop framework is emulated.
One recorded failure
