An empty panel is displayed on Detail when Resource fields only contain Panels

[WillyReyno]

• Laravel Version: 8.83.8
• Nova Version: 4.2.2
• PHP Version: 8.0
• Database Driver & Version: MySQL 8.0

Description:

When Resource fields only contain Panel(s), an empty Panel appears at the top of the Resource Detail page :

If another field is added within the fields() array, the empty panel disappears:

Detailed steps to reproduce the issue on a fresh Nova installation:

• Create a resouce
• Within the fields() method, declare one or more panels (without any field at the root of the array)

I am hesitent to fix this issue because it would create more visual issues rather than fixing anything. Default panel are special panel used as primary placeholder and has custom toolbar.

Just show how mess up it can be by adding Panel as first field.
