Nice fix @fengga . Just see that a few unit tests need to be updated.
In MSAL C++, interactively calls always add "haschrome=1" to avoid such kind of unexpected back buttons on the first page, and this way is also recommended by ESTS folks.
Intriguing finding. It feels like folklore because even the name of that workaround - "haschrome" - does not make much sense. :-)
On a more serious note, the current feature branch name is "fixEmbeddedbrowser", however, now I realize that the same mysterious Back-button behavior also applies to Firefox as system browser: it shows up by default, and disappears when using haschrome=1. But I am not aware of other complain, presumably because that default Back button is understandably perceived as a Cancel. So, I suppose we do not have to propagate this change to all other MSALs, do we?
