Failed to install an app with classic confinement using Softwarre Store

[Danilo Alculete]

Tried to install an app with classic confinement using software center and it failed with the error in a window

========================
Instalation of Visual Studio Code failed. If the problem persist contact your software provider.
Details:

Detailed error from the package manager follow:
snap returned status code 400: Bad Request

=======================

Then I tried installing through CLI and had the error below
===
error: This revision of snap "vscode" was published using classic confinement
and thus may perform arbitrary system changes outside of the security
sandbox that snaps are usually confined to, which may put your system at
risk.

   If you understand and want to proceed repeat the command including --classic.
===

and it worked using --classic confinement on CLI.

Shouldn't this warn or auto selects the confinement that was set when packaging?
