Conflict of titlepage-pdf with margin figure captions

[dkStevensNZed]

I'm using titlepage-pdf format for a quarto document. It works great except that when I use that format, the captions for margin figures are clipped to ~0.75" and the caption is hyphenated and wraps around to the next line. If I use the standard pdf format, the caption extends across the full width of the margin before wrapping. I've attached the pdf file produced using titlepage-pdf (see p. 2 of the file)

Seems to have to do with the \usepackage{geometry} call. I can replicate with format: pdf by adding geometry. titlepage-pdf has a \usepackage{geometry} call backed in.

After adding the geometry include with no success,I tried your example with the same result. Then I took out the documentclass: scrartcl and the result was correct, as I had gotten with 'just' pdf format. When I change the format from pdf: default to titlepage-pdf: default, the shortened caption came back. Is pdf with 'documentclass: scrartcl' the same as titlepage-pdf?

A test case. Has to do I think with geometry package in LaTeX.
