Missed larva selections

From the global viewer view, with all the larvae shown, on left-clicking on a larva, the view zooms in on the larva under the mouse pointer.

Problem: Some clicks/selections are ignored/missed. This typically happens when clicking on an active area as shortly as possible after the mouse pointer reaches the area.

As this seems to be related to some server-side latency, hopefully the issue can be fixed with a system image. Precompiling key parts of the code may be another option.

Another possible cause to investigate is some observable wrapped using Observables.async_latest.
