This is a relatively recent change (r85348, October 2023). Previously,
R CMD build detected non-build-time dynamic content in the package
documentation and built the manual automatically. Nowadays I think you
have to set BuildManual: yes in your DESCRIPTION before building the
package. (There's R CMD build --no-manual, but I'm not seeing a command
line option to override it from "no" to "yes".)

Correct, that must be what's producing the render-stage dynamic content:
