Opening browser console in a session with ~8 windows ( some of them have lots of tabs) is slow. I think it didn't used to be this slow.

Lots of time is spent running React js code. And looks like also some very slow reflows from explicitly flushing layout from JS (https://searchfox.org/mozilla-central/rev/559b25eb41c1cbffcb90a34e008b8288312fcd25/devtools/client/webconsole/components/Output/ConsoleOutput.js#182-188)
