From Ionic React Documentation - "Ionic might keep the page around in the DOM"
"For instance, componentDidMount fires the first time a page is displayed, but if you navigate away from the page Ionic might keep the page around in the DOM, and a subsequent visit to the page might not call componentDidMount again. This scenario is the main reason the Ionic lifecycle methods exist, to still give you a way to call logic when views enter and exit when the native framework's events might not fire."
