generated checkboxes are invalid (removed when roundtripping through pdf2ps -> ps2pdf; fail to display in a number of PDF viewers)

I have

\documentclass{article}
\usepackage{hyperref}
\begin{document}
\begin{Form}
\fbox{\CheckBox[name=foo,checked=true]{}}
\end{Form}
\end{document}

This checkbox shows up fine in Adobe Reader, but the checkbox is unchecked in Chrome's PDF viewer, and does not show up at all in Firefox's PDF viewer nor in SumatraPDF. Worse, if I run pdf2ps foo.pdf foo.ps and then run ps2pdf foo.ps foo-ps.pdf, the resulting PDF file does not contain a checkbox. Note that pdf2ps warns with

   **** Error: Required entry /BBox not present in Form.
               Output may be incorrect.
               Output may be incorrect.
   **** Error: Stream object is missing the stream data.

Note also that when I open the original PDF in Adobe Reader, when I go to close it, Adobe Reader asks me if I want to save changes, suggesting that it's corrected some invalidity in the pdf behind the scenes. Indeed, if I do this, the resulting PDF displays checkboxes correctly in all PDF viewers, and displays the checkbox when I round-trip through a .ps file.

Here are all the generated files:
Assuming I named the above foo.tex, then:

1. pdflatex foo.tex gives foo.log and foo.pdf
2. Opening foo.pdf:

• in Chrome gives:
• in Firefox gives:
• in SumatraPDF gives:
• in Adobe Reader gives:

3. Running pdf2ps foo.pdf foo.ps; tar -czf foo.ps.tar.gz foo.ps; ps2pdf foo.ps foo-ps.pdf gives foo.ps.tar.gz and foo-ps.pdf and on the command line says

$ pdf2ps foo.pdf foo.ps

4. Opening foo-ps.pdf in Adobe Reader shows:
5. Re-opening foo.pdf in Adobe Reader, and doing File -> Save As -> foo2.pdf gives: foo2.pdf
6. Opening foo2.pdf:

• in Chrome gives:
• in Firefox gives:
• in SumatraPDF gives:

7. Running pdf2ps foo2.pdf foo2.ps; tar -czf foo2.ps.tar.gz foo2.ps; ps2pdf foo2.ps foo2-ps.pdf gives foo2.ps.tar.gz and foo2-ps.pdf
8. Opening foo2-ps.pdf:

• in Chrome gives:
• in Firefox gives:
• in SumatraPDF gives:
• in Adobe Reader gives:

No source file or test is named. Start with the minimal LaTeX example using hyperref's \CheckBox, run pdflatex, and inspect it in the reported PDF viewers before and after pdf2ps/ps2pdf. Done means the generated checkbox remains visible and checked across viewers and survives the PostScript round trip without the reported PDF errors.
