Safari 16.0 will not load tabs in the background

I've just upgraded to Safari 16.0 under OS 12.6, and the tabs have, once again, stopped loading in the background. I have a group of tabs that I click to load up all the URLs for the day. I want them all to load at once—not once I've actually clicked on any given tab. This didn't work for a while under Safari 15, but then it did. Now we're back where we started . . . unless you can help us!

Is there a way to get Safari 16.0 to load tabs in the background?

Thanks!

It seems it is the same issue as last time with Safari 15 (Safari 15 doesn't load tabs in background - Apple Community), and this time the past solution from https://www.reddit.com/r/MacOS/comments/9iqq09/mojave_safari_tabs_not_loading_in_background/ is not working, or at least not on my setup (M1 macOS 12.6, latest updates, safari 16):

Make sure Safari is quit. Open Terminal, type the following command, and hit return:

defaults write com.apple.Safari IncludeInternalDebugMenu 1

Re-open Safari. You now have a "Debug" item in the toolbar to the right of "Help." Go to that, then under "Miscellaneous Flags," click "Disable Background Tab Suspension."
Now quit Safari, go back to Terminal, type the following command, and hit return:

defaults write com.apple.Safari IncludeInternalDebugMenu 0

Re-launch Safari and you're all set.

PS: I also tested latest Safari Technology Preview (Release 153 (Safari 16.0, WebKit 17615.1.4.1)), compared to current Safari version under macOS Monterey 12.6 (Version 16.0 (17614.1.25.9.10, 17614)), and we have the same issue there, no background tabs loading (yet).
