Media: Fix admin image cropping calculations.
The admin image editor crop function introduced rounding errors by using a scaled image to calculate values. Fix uses the image at 100% scale for calculations. Also avoid recalculating selection when the selection position is changed, and prevent incorrect values after scaling or restoration. Previously committed in [58456] and reverted in [58571]. The revert was due to a misattributed test failure. Props Jossnaz, johnillo, shailu25, rachelbaker, sudipatel007, joedolson, kevin940726 , andrewserong, hmbashar. Fixes #32282. Built from https://develop.svn.wordpress.org/trunk@58915 git-svn-id: http://core.svn.wordpress.org/trunk@58311 1a063a9b-81f0-0310-95a4-ce76da25c4cd
