On mobile, tapping a tooltip-wrapped link that opens a new tab leaves the tooltip stuck visible after returning to the original tab, because neither

useTooltipBase.tsx: Inside the existing visibility-gateduseIsomorphicLayoutEffect(which already owns thekeydown/Escape listener), register avisibilitychangelistener ontargetDocumentfromuseFluent_unstable(). WhentargetDocument.visibilityState === 'hidden', call the samethisTooltip.hide()path used by Escape soonVisibleChangeand controlled-state semantics are preserved.
