Subject: [PATCH] [AltStatusBar] Fix when showing (almost) empty (#12003)

With enabled battery percentage shown and some other (e.g. reading percentage) the alt status bar shows the expected line. But when disabling everything except battery percentage, then the reading percentage keeps being shown.

So when using this `self:page_info_override` caching trick, we have to restore the cre default again.
