Relevant logs and/or screenshots

Possible fixes

After sending a comment, we refresh the view only with the discussions. But we should pass in the label events the same way as when we initialise the webview.

A naive fix would be just to fetch the label events as we fetch the comments. However, the webview implementation seems to be very inefficient, and we should think about some optimisation when implementing a fix.
