Does get/setWindowValue persist across browser restarts?

Hi,

If I use the sessions.setWindowValue and sessions.getWindowValue api, do
the values persist across browser restarts? The MDN documentation does
not give an answer:

I’d like to save some settings on a per-window basis but the window IDs
are not the same across browser restarts, so looking for another way to
identify which settings belong to which window.

Thanks,
