An ObservabilityHandler instance is created and associated to every UI instance, so its identifier could be used to group front-end traces that come from the same browser tab.
ClientInstumentation can add the ObservabilityHandler identifier as an attribute to all the processed spans.
This should also work fine with @PreserveOnRefresh, since the UI instance will not change on page reload and the ObservabilityHandler will not be recreated.
