On several occasions I've noticed that when loading a CL the "tryjob" status does not load. Opening the DevTools has several errors in such cases.

The UI thought displays "No Tryjobs" which is very confusing. I keep having to reload CLs to figure out if the the status could not be fetched, or if in fact I never spawned tryjobs.

An error message should be displayed to avoid any confusion. (And ideally the status fetching should not fail that often).
