She doesn't seem to be aggressive, just inquisitive, but with two cubs to protect that can of course change quickly. But as long as the human inhabitants stay on their side of the window, all seems to be well, give or take periodic re-purchases of pool floats obviously not designed to withstand brown bear claws and teeth.
I've seen black bears this oblivious to human civilization, but not brown bears (I've learned that a Grizzly is a brown bear sub-species, but Californian Grizzlies as another sub-species are extinct, so she and her cubs are brown bears, not Grizzlies).
If this happened in Germany in the few regions where we still have brown bears a state of national emergency would have already been called.
West Coast relaxation about things can be admirable sometimes.
