I noticed an issue when trying to use s-table-row’s clickDelegate feature in Polaris web components: s-link elements are not triggering the navigation when invoking their click function (which is what clickDelegate does). However, that’s only the case for embedded apps.
You can try that out very easily in any (embedded) app that’s using the Polaris web components: search for an s-link that has the id property set, then run document.getElementById(“<ID>“).click() in a Web Inspector console - nothing will happen.
