Example request:

{
	consumer: "GERRIT",
	gerritDetails: {
		change: "playground%2Fgerrit-tricium%2Fdemo~master~I362c3eebfda853f8f22df3b98b2c0c572ae00f66",
		host: "chromium-review.googlesource.com",
		project: "playground/gerrit-tricium/demo",
		revision: "refs/changes/63/899863/5"
	}
}

Response:

{
	"runId": "5723348596162560",
	"state": "RUNNING",
	"functionProgress": [{
		"name": "GitFileIsolator",
		"state": "RUNNING",
		"swarmingUrl": "https://chromium-swarm.appspot.com",
		"swarmingTaskId": "3b86383d14952f10"
	}, {
		"name": "Hello"
	}, {
		"name": "Spacey"
	}]
}

What this means is that while analyzers are pending, they are shown in a white-background unstyled box. They could be shown in a colored box with an icon.

Possible fixes: The Progress response should included state: PENDING. Perhaps the plugin should also use PENDING as a default state if nothing is present in the response.
