Hello !

Here is a link to a little project which has the issue : https://github.com/BenoitMonchanin/ionic-demo You can just run by cd ion-modal_navigation, little npm i then ionic serve and the first page will be it !

Simply use the "Open Modal" button and navigate through modals using Tab and Space with buttons, you'll see the issue.

Thanks for the report. It looks like the issue here is the previously focused element (the ion-button on Page1) is hidden, so the browser moves focus to the body. This is normally fine when used outside of ion-modal (since the body should have focus), but when used in ion-modal the focus should be moved to the modal.
