Internal PDF import fails to import image from Matlab PDF

I have a simple PDF file consisting of a single image. Import using poppler/cairo works as expected, but the internal import option fails to display the image correctly. The svg:image tag's xlink:href attribute has different values for the two different import options.

Steps to replicate

• Open bug.pdf in Inkscape
• Select default method (Internal import) and hit OK

What happened?

• Image not visible.
• There is one svg:image in the document but it appears transparent and has a different xlink:href values than poppler/cairo (which works.

What should have happened?

• Image imported correctly

Sample File: bug.pdf

Version info

Tested in Windows 10 using Inkscape 1.1.1 and 1.1.2 (64 bit versions). (This may not be relevant, but PDF was generated in Matlab)
