how can I constrain a crop using 'photos' on a mac?

I'm using the "Photos" application on a Mac. MacOS 10.13, High Sierra.

I want to set a custom proportion for a crop (Crop/Aspect), and constrain further resizing to that proportion. For instance, set a custom crop to landscape 7:4. And somehow 'constrain' it, so that when I resize the crop area it maintains that proportion.

Is there some way to do this? (Didn't this use to be an option in earlier versions?)

MacBook Air, macOS High Sierra (10.13.6)

It should still work. While cropping, select "Custom", then click the Landscape rectangle and enter the aspect ratio 7:4, like this:

When you change the size, the cropping rectangle should remain constraint to this aspect ratio.

Hmm. Maybe it "should" work, but it doesn't. Your screenshots illustrate how I set a custom proportion for a crop. But setting it has no subsequent constraining effect on the cropping rectangle.

But here is what sort of works:

On the Crop tab, set the custom proportion
adjust the rectangle, in terms of relative scale and desired portion of the image (it'll be all floppy, not constrained)
click the "Custom" option on the list. The rectangle then snaps to the desired proportion.
