Description

[Nicolas Chevobbe [:nchevobbe] [PTO - back January 24]]

Steps to reproduce

1. Navigate to data:text/html,<meta charset=utf8><style>:root{--a: (min-width:680px); }</style>
2. Open the inspector

Actual results

Rules view is blank. There's an error in stdout:

new TypeError("can't access property Symbol.iterator, parts is undefined", "resource://devtools/client/shared/output-parser.js", 936)

which seems to come from https://searchfox.org/mozilla-central/rev/45d6f8bf028e049f812aa26dced565d50068af5d/devtools/client/shared/output-parser.js#936

this.#getCurrentStackParts().push(...parts);
