When one applies without being compliant with the residency obligation, the timelines go out the window. So no-one can tell you.
The fact they requested more information is (IMO) actually a good sign, they're looking at substance (and she's also been in Canada and still is, probably with sufficient documentation to show it).
BUT: most of the waiting is being in a queue, with (probably) quite limited resources, and this actually requiring some work to check the submission (when officers are under pressure to do volume). The queue might take quite a while - or not.
It really is a VERY good example of why it's better to wait eg the extra four / five months before submitting the renewal app - in the end it's usually faster.
