Animate task surface when attempting to snap resize from currently snap resized bounds

Resolving an edge case where if a desktop window was already snap resized, and is attempted to be drag snap resized again, the transition handler would see that the task bounds don't change so nothing would happen. Now in this case, we instead animate the task surface going back to its original bounds (similar to non-resizable case, but with no toast shown)
