Pinned tabs in Safari and Google Authentication

I use a Safari Pinned Tab for Asana. Occasionally, I am prompted to re-authenticate and since I use Google Authentication, Asana jumps to a new tab to authenticate. This leaves my pinned tab at the Asana Login screen and I have to copy the URL back to the pinned tab after logging in.

Other sites can initiate Google Authentication without jumping to a new tab, can Asana do that also? There is really no value in going to a new tab to use Google authentication - even if I wasn’t using Safari pinned tabs.

Please change the Asana login screen so that the Google authentication button does not go to a new tab.
