I open a PNG with Preview, then drag another one into the sidebar, and then choose Export to PDF. The resulting PDF has only one page.
I tried again, after selecting all pages -- same result.
How do I export a multipage PDF?

The quick workaround is to go to Print, then save as PDF from there. This will save all pages opened in the same window.
