OK, I was able to try @kovidgoyal's suggestion right now, and 7.18 does indeed work with this setting:

When I set it back to Wayland, it goes back to its not-opening behavior.
It is strange that it worked great for me under Wayland through 7.16, and only broke with 7.17.
I guess this solves the issue for me. Thank you!
