callback method of oAuth2 strategy not working in SPA

[girlcheese]

Version

4.8.2

Reproduction link

d580649

Steps to reproduce

Configure your site to use an oAuth2 scheme, build a Nuxt site as an SPA (No SSR) and observe that logging in with the 3rd party provider lands you on the callback page - with parameters from the provider in the hash portion of the URL. The linked commit shows that support for SPA was reversed to support for SSR only in a recent PR.

What is expected ?

oAuth2 login should work for a Nuxt site running as an SPA and as a universal site with SSR

What is actually happening?

No support for oAuth2 login when static generated site is deployed
