Safari Develop menu with Extension Background Content and example.org

I believe this issue started with iOS 17.4 and iPadOS 17.4. It worked as expected before.

I can reproduce on both my iPhone and iPad. Steps to reproduce:
1) Connect iOS device to Mac
2) In mobile Safari, open https://webkit.org
3) In desktop Safari, select the iOS device in the Develop menu
4) Select webkit.org to open the web inspector
5) Close the web inspector
6) In mobile Safari, close the window
7) Open a new window, and open example.org
8) In desktop Safari, select the iOS device in the Develop menu

Expected results: example.org appears in the menu

Actual results: example org does not appear in the menu

See the attached screenshots.

You have to force quit mobile Safari in order to see a new window in the web inspector.

There are other variations of the issue. For example, in step 2, open two windows, one with webkit.org and the other example.org. But the Develop menu will only show the first website, not the second.

I believe the issue depends on the iOS version and not the macOS or desktop Safari version. I was able to reproduce with two Macs, including both Sonoma and Ventura, as well as both desktop Safari 17.4 and 17.2.
