If you make a lasso selection that goes off the edge of the canvas then press 'Ctrl T' the Transform box will include a virtual wrap around selection on the opposite side of the canvas.
To reproduce: Draw something on a Layer near the edge of the canvas > Make a lasso selection that encompasses what you have drawn but also goes off the edge of the canvas > Press Ctrl T > Notice the transform box extends to the opposite side of the canvas.
Expected result: Transform box will ignore the lasso selection that is outside the bounds of the canvas.
