I posted this over in the Polaris section, but nobody is responding. Maybe it goes here?
I have a form with data-save-bar active on a page that also has Polaris web components s-page with navigation breadcrumbs (using the slots). When changes are made and the save bar is showing, clicking on a breadcrumb results in successful navigation and simultaneously the save bar shakes and remains on the new page – where it has no effect and can no longer be dismissed.
It seems like the save bar should be intercepting the breadcrumb navigation, but it isn’t. Likely this is because the interaction between web components and app bridge isn’t quite right.
