On a MAC, the lost focus event is not triggered when the focus shifts away from the browser (This happens on all browsers (Safari, Chrome or Firefox))to another window when clicking on a search textbox or notification panel. This has been observed in:
MAC OS Big SUR Version 11.2.1
MAC OS Big SUR Version 11.5.1
MAC OS Big SUR Version 11.6
MAC OS Monterey 12.1
MAC OS High Sierra Version 10.13.6 is the only MAC OS where the lost focus event is triggered when clicking away from the browser to an OS component such as a textbox or notification panel. Is it possible to restore the lost focus event on the above versions of MAC OS?
