Do we really want to hard code this test id into the component? I'm not sure what a better way to do it would be, but I don't love this, and the fact that there isn't a better way is probably signaling a lack of a11y on this. Would love @thatblindgeye's thoughts on this.

Do we want to add a demo? Probably want to add a prop comment. Otherwise looks fine to me!

@rebeccaalpert i replaced a few examples with an interactive one

Thank you! Surge doesn't have it for whatever Surge-y reason, but localhost looks great.

Mentioned in a Slack convo and just commenting here for future reference, but regarding a potential implementation where a consumer wants no icon + no measure + status colors, we could probably recommend:

• if the status color isn't critical and is really more visual in nature (e.g. maybe there's no actual error or warning message or anything), then the progress bar itself would probably suffice as a means to convey whatever message is meant to be conveyed (e.g. "This thing is almost full")
• Otherwise, strongly recommened an icon be used, or at the very least a visible measure value if perhaps helper text is provided that has its own error icons.
