[Bug Report][3.3.12] VAppBar scroll behavior "hide" not keeping extension slot visible

[carlosyan1807]

Environment

Vuetify Version: 3.3.12
Vue Version: 3.3.4
Browsers: Chrome 115.0.0.0
OS: Windows 11

Steps to reproduce

Create a VAppBar component with scroll-behavior="hide" and an extension slot.
Observe the behavior when scrolling down.

Expected Behavior

The default slot area should hide as the user scrolls down, but the extension slot should remain visible, as stated in the documentation.

Actual Behavior

Both the default slot area and the extension slot are hidden, which doesn't match the expected behavior as described in the documentation.

Other comments

According to the documentation
https://vuetifyjs.com/en/components/app-bars/#scroll-behavior

hide: The default slot area will shift up and hide as the user scrolls down. The extension slot remains visible.

I am not sure if this is the intended behavior.

Thanks.

It sounds like there are supposed to be two values here for scroll behavior:

• hide the extension slot remains visible
• fully-hide the entire app bar is hidden including the extension slot
