Upgrading from MSAL-angular 0.x.x to 1.1.2 on the way to 2.x.x, acquireTokenSilent

[ingar-hillestad-4ss]

We are trying to upgrade our Angular cli version, and on the way there we are upgrading the MSAL-angular library from version 0 thru 1.1.2 (msal 1.4.4) and eventually to 2.x.x.

But as far as I can see there is a major issue with that, starting in acquireTokenSilent(AuthenticationParameters), and how that has changed.
We are using Azure AD with federation, and because of that, we need to provide domain_hint in the url togheter with the login_hint. If not, we are just ending up with the well-known error relating to x-frame-options header not set, and getting the response times out.

After some digging in the library-code, I found that even though domain_hint is supplied in extraQueryParameters in the request, the call to ServerRequestParameters.generateQueryParametersString() explicit remove/ignores it. Those lines of code break the needed functionality. From what I can see, that code is the same in the newest version, so I can't just ignore it for now.

Are there any solutions to this that I can't see?
