What is the bug?
In Opensearch Dashboards URL hash encodes the state of a visualization (state could be the filters to apply, the time range etc). Currently for OpenID Connect based authentication when user logins/re-logins the url hash is being dropped because of redirecting to the IDP.

How can one reproduce the bug?

Steps to reproduce the behavior:

1. Setup OpenID Connect based authentication
2. Open any dashboard
3. Copy the URL
4. Logout
5. Open new private window
6. Paste the URL
7. You are redirected to /app/dashboards (dashboards overview)

What is the expected behavior?
The state of the dashboard/visualization must not be lost.
