If the web socket is closed task progress messages are lost. If the "completed" or "aborted" message is among lost messages a progress notifications remains freezed.
Add a setTimeout/clearTimeout invocation for each WS message received. After 10 seconds, if no further message comes send an HTTP GET request with getTaskStatus() to verify the task status from API server.
If the HTTP request fails, try again after 10 seconds. If it succeedes generate a synthesized progress message that completes the task progress at 100%.
