Orthographic/perspective at view rotating. 3d view

Hello. in 2.79 Blender, many times i like to toggle view from "perspective" to "ortographic" to some operations. I often adjust to a pure side or front orthographiv view with "Alt" key, and then i often to rotate the view. When i do this action, in Blender 2.79, the view remains at orthographic mode, but when i do this action in Blender 2.8, the view changes to perspective inmediatly. I think that this action it should be like in Blender 2.79.

I leave a vídeo to show the action.
