The functionality of snap with constraints relies on the position of the transformed object. Previously, snap to grid with constraints was restricted to the Move operation. Consequently, the 'Set Snap Base' mode, as well as other transformation modes, failed to compute the moved position. As a result, it lacked support for snap to grid with constraints and would even crash under such circumstances. The solution involves eliminating the reliance on the Move operator and instead calculating the position based on mouse position.
