Confusing output when running two builds concurrently

[OliverJAsh]

Version

v4.0.0

Reproduction link

Steps to reproduce

Reduced test case: https://github.com/OliverJAsh/webpack-concurrently/tree/bar

Note: you must use the bar branch.

Run yarn and then npm run compile.

We are running two webpack builds concurrently. Each webpack build has its own instance of the WebpackBar plugin, with a unique name (client and server).

What is actually happening?

• We see two bars, but a single bar will flicker between client and server.
• One of the bars never updates.

What is expected ?

I would not expect this flickering—each build should have its own bar and it should not interfere with other bar instances.
