We've implemented this Timeline within a project, but testers have raised that there are inconsistences around how records open (some within a SF tab and some within a completely new browser tab).
In the LinkedOutputText LWC, when isExternalServiceData is false, it defaults to this code which opens the record in a new browser tab:
window.open(${this.baseUrlForRecordDetail}/${this.recordId},'_blank');
Why has it been done implemented like this? To navigate to the record using navigation mixin, all you need is the recordId and object name which has already been set via the Apex Class data provider type. We've had to set multiple Apex Class providers to false for "isSalesforceObject", otherwise we cannot get the child configurations to display correctly, even thought they're still Salesforce objects.
Ideally we want consistency with how records are being opened, and this doesn't seem quite right. Is there something that can be added to check if it is indeed a recognised Salesforce object, and still be able to navigate with the mixin?
