The issue is if she was reported she would have already lost her status and wouldn’t have qualified to apply for the extension when she did. The other issues is IRCC is now looking back to see when people started to be non-compliant with their study permit. You basically have to wait and see what happens and whether restoration is possible.
I am expecting the rejection because of that, but how does an applicant know they lost it? She just applied for an extension.
Will this affect the sponsorship? She won't have status either way by the time we get married and apply for sponsorship
