The AsciiDoc just needs to happen to have a math line at the end of a page. Try this:

= Some Document
:stem: latexmath

== Just 1 chapter

stem:[\displaystyle \frac{1}{2}]

I cannot reproduce this issue on the main branch. Here's the PDF produced: test.pdf

[jhannwong]

Your test.pdf has enough math lines to just about fill up the 1st page. Try adding more so that they overflow to the 2nd page?

It also works test.pdf
Do you use a custom style? Could you please try with the latest version?
