AI 26.4 PDF changing crop and size copy pasting from one document to another

[steenz28028789]

Open multi-page PDF with cropmarks

Copy opened file

Paste to new document (large ai - not sure if specific)

Pasted PDF is now cropped to the crop marks, but at the overall dimension INCLUDING crop marks from the previous document. 

So it's taking the visual area, cropping it, and stretching it to the artboard size when pasted. 

Thanks for that 90 minutes of lost time adobe. 

Rolled back to version 26.2.1 and it's working as it should.

Why would I still have a broken version installed, just to show you?
