Inspector keeps deleted asset displayed

[Flavelius]

Godot version:

3.2.3.stable.mono.official

OS/device including version:

Windows 10 x64

Issue description:

As the title states, the inspector still displays deleted assets after they should have gone.
See: https://streamable.com/uywpuf

Steps to reproduce:
Double click an asset (material for example) so it is displayed in the inspector, then delete it. See the inspector still diplay it.

See also godotengine/godot-proposals#1550, which is the same issue but for scripts.

The current behavior may be considered intended. Maybe you didn't actually want to remove the resource and want to save it to recover it.

There's already a confirmation dialog for deleting assets (which is also more than unity even does to help with that and even there it's not needed). If one really doesn't want to delete an asset clicking cancel is the naturally best option.
Normally when editing an asset the changes are directly persisted and in this case my intuitive expectation would be that editing the fields now throws errors etc because the file just vanished behind the scenes. And this expectation (or the lack of the expected result too) makes it feel buggy/unintended. So it's probably more a case of look&feel, but maybe this can be given another thought when that side of the development becomes focus again.
