Dear list,

I have the following source:

  \nopdfcompression
  \setupinteractionscreen
    [width=max]
  \setuplayout
    [standard]
    [backspace=.7\textwidth,
     cutspace=\cutspace,
     width=middle]
  \starttext
  \startmakeup[page]
  \null
  \stopmakeup
  \startmakeup[standard]
  \null
  \stopmakeup
  \stoptext

Boxes are defined in the following objects:

  3 0 obj
  [ 0 0 595.275590072 841.88975789 ]
  endobj

  5 0 obj
  [ 0 0 595.27559 841.889758 ]
  endobj

  8 0 obj
  [ 0 0 968.199847 841.889758 ]
  endobj

Page 1 has /MediaBox redirected to object 3 and /CropBox redirected to
object 5.

Page 2 has /MediaBox redirected to object 3 and /CropBox redirected to
object 8.

I’m not sure whether the oversized /CropBox in the sample above is a
bug triggered by the use of "\setupinteractionscreen[width=fit]".

From the PDF–1.7 specification
(https://opensource.adobe.com/dc-acrobat-sdk-docs/standards/pdfstandards/pdf/PDF32000_2008.pdf#page=636):

  The crop, bleed, trim, and art boxes shall not ordinarily extend
  beyond the boundaries of the media box. If they do, they are
  effectively reduced to their intersection with the media box.

https://wiki.contextgarden.net/PDF_Boxes displays an image of (what I
guess) the ordinary case: /CropBox fits inside /MediaBox.

Could anyone be so kind to confirm the issue or to explain the
rationale behind the oversized /CropBox?

Many thanks for your help,

Pablo
