I recently discovered that when using "Settings > Paste from previous" that LRc calulates the aspect ratio for the crop from the image dimensions and ignores the user set aspect ratio such as Original, As Shot, etc.
This creates issues with images edited outside of LRc might have their aspect ratio altered as LRc sees it as a different aspect ratio from the original due to interger rounding. It would, for example, crop a 6000x4000 image to 5999x4000 but it also the case that just because one image is 1:1 outside of LRc it doesn't mean LRc should force that ratio upon other images.
LRc should be consistent with the user facing values the same as it does with the White Balance for example, which doesn't simply paste the Kelvin value from the previous image, it respects the displayed setting, eg. As Shot, Daylight, etc.
This would help greatly with workflows that involve editing work in PS before returning to LRc for further global tweaks. For example, when replacing backgrounds it's important that global edits are all done at the same time for continunity and often these values just need to be pasted from the previous edited image.
In summary, LRc should only alter the crop on images when pasting settings from an image the user has intentionally cropped in LRc.
