PDF diagram with labels

Ghostscript is used by pdfcrop (https://www.ctan.org/pkg/pdfcrop) to determine the bounding box of a PDF file (attached). In Ghostscript 9.27 the bounding box is different from Ghostscript 9.26 which results in the labels of the diagram being cut off.

Ghostscript is called like:
> gs -sDEVICE=bbox -dNOPAUSE -dBATCH -f unnamed-chunk-2-1.pdf

Here's the relevant output from Ghostscript 9.26:

    %%BoundingBox: 4 15 439 300
    * Page 1: 4 15 439 300
    %%HiResBoundingBox: 4.212000 15.102000 438.135034 299.825991

... and here is the (quite different) output from Ghostscript 9.27:

    %%BoundingBox: 12 11 439 293
    * Page 1: 12 11 439 293
    %%HiResBoundingBox: 12.708000 11.412000 438.135034 292.031991
