Crop tool crops on mouse click

PS 20.0.1  After setting a crop using the crop tool, the next mouse click anywhere will execute the crop, unlike previous versions which required a keystroke (enter or return). This stops me from setting guides to the crop area then discarding the crop as I used to do (so that I knew the limits of the area I needed to work on). The workaround* I've found takes more time, especially if you want to return to the precise pixel dimensions of the original image (for compositing later, for example) or if you need to set more than one possible crop (which is usual for me - I need to prepare images for at least two different aspect ratios).

*Crop without discarding pixels, set guides to image edges, recrop back to original image.
