Generate Physics and Collider settings for a Mesh are lost every time the 3D Scene is Re-Imported

Issue description

When importing FBX/GLTF files, and selecting Meshes from the Scene in the Advanced Import Dialog, and then checking "Generate Physics" and customizing "Body Type" and "Shape Type", the settings are correctly applied in the first Reimport action.

But subsequent reimports using the Import tab or the Advanced Import Dialog, end up resetting the Physics settings. The issue is random, sometimes it resets via the Import tab, sometimes via the Dialog.

Steps to reproduce

• Import any FBX/GLTF file into the project.

• Double click it to open the "Advanced Import Settings" Dialog

• Click any MeshInstance to be imported, click Physics

• Change Body Type and Shape Type to a non-default value, example:
  

• Now click Reimport

• Right click the file, New Inherited Scene.

• In the Scene tree, check that the correctly physics Nodes were added:

• Now, with the mesh file selected in the FileSystem click the Import tab and click Reimport.:

• Right click the file again, New Inherited Scene and make sure you go to the Scene tree of the new scene.
• The collision shapes are gone OR they are back to the default one (Trimesh Static)

• SOMETIMES, the shapes are still regenerated. But then, if you re-open the Advanced Import Settings dialog, the physics settings are gone too:

Minimal reproduction project

Any blank project with a FBX file will do, but in any case here it is a project with a simple FBX file:
PhysicsImportSettings.zip

Confirmed in 4.0rc3

Okay so what seems to be happening is the import panel is remembering what settings it saw from before you had opened the Advanced... window.

If you select a different object and then select back, it will now "Reimport" using the new, current settings.

A mitigation might be to reload or deselect the current object from the import settings every time the advanced importer is closed.
