Sphinx 5.3.0 to Sphinx 6.2.0 has a bug where nested content in an ObjectDescription content block has its error position reported incorrectly due to an oversight when they added nested section support to this directive.
(This bug is present in Sphinx's own Python and C domains; test it yourself by creating a py:func directive and creating a syntax error in the directive's content block.) To avoid overriding and re-implementing the entirety of the run() method, a workaround is employed where we parse the content block ourselves in before_content(), then null the content block to make Sphinx's own parsing a no-op. Then, in transform_content (which occurs after Sphinx's nested parse), we simply swap our own parsed content tree back in for Sphinx's. It appears a little tricky, but it's the nicest solution I can find.
