Make a sharing behavior the same for both Office files types and custom files types.

Current behavior:
File Handlers 2.0 allow to register custom files types (that can be configured to open by custom web applications) for Office365 tenant.
When you share this custom file type, a person who receives sharing link will download the file when after clicking on the link. Instead of downloading, the file should have been opened in a custom web application that the file is configured to open.

For instance, for Office file types, when a person clicks on a shared Office file - it is opened in an Office app.

Desired behavior:
For both Office files types and custom files types, when clicking on a sharing link the file should be opened in the application that opens this file.
