Bad behavior of wp_nav_menu

[369work]

The menu of the theme that was displayed correctly up to 6.7.1 breaks down in 6.7.2.
I investigated the cause and found that in 6.7.2, wp_nav_menu is surrounded by a div by default. Until now, div was not supposed to be used unless a container was specified.

6.7.2-alpha-59547

6.7.1 no problems

It looks like for 6.7.1, you have a menu assigned to your menu location, but in 6.7.2-alpha-59547, there is no menu assigned, so it is falling back to the value of fallback_cb which is wp_page_menu?

It is a known issue that the behavior of wp_page_menu is sometimes inconsistent with the behavior of wp_nav_menu. See: #18842, #14614, #13998.

I don't think anything changed for wp_nav_menu (or wp_page_menu) between 6.7.1 and 6.7.2-alpha-59547.

Personally I prefer to set fallback_cb to FALSE to avoid dealing with wp_page_menu entirely:

You could also write your own custom fallback function.

Thank you.
It appears that's the case.
This happened when I put a theme I was creating into a WP that had themeunitdata in it.
This was very helpful.
Thank you.
