Continuity markup partially broken in Ventura

In macos Ventura, with an iPad 11" (3rd Generation) and a 2018 MB Pro, the continuity markup works for images only. For PDF files it is not working (there is no markup icon in the toobar when a PDF file is quick-previewed). When I quick-preview an image file (like a screenshot) the markup icon appears and the file opens on the iPad, just like it used to.

Both devices are 100% up-to-date

Anyone else having this issue?
