Having only the status dot was hard to read. It requires you to learn &
remember the different colours, or to mouse-over and wait to see the
tooltip. For accessibility, we shouldn't be using just the colour to
convey information in the interface.
The tasks table resize function is called via `this.$nextTick()`, which
means that the component can actually already be unmounted by the time
the actual function call is performed. This is now detected & handled.
