How can I specify the window size for Emacs on a Mac?

I used to be able to launch [Emacs](https://emacsformacosx.com/) version 28.1 on macOS from the command line in XQuartz terminal window like so:

/Applications/Emacs.app/Contents/MacOS/Emacs --geometry 109x65 &

After upgrading to version 29.1, the geometry option appears not to be respected any more. Instead, Emacs with a default, smaller window size appears in the background, behind the rest of the XQuartz terminal windows. How do I fix this?
