Description Devin Rousso 2019-04-03 13:26:54 PDT
1. inspect any page
2. go to the Elements tab
3. context menu on the <body>
4. Break on... > Attribute Modified
5. evaluate `document.body.style.setProperty("--a", "0")` in the console
 => JavaScript should pause on a Console Evaluation with the above code highlighted
6. go to the Elements tab
 => the <body> has a `style="--a: 0;"` attribute

This works as expected (e.g. the breakpoint pauses before the modification occurs) for any non-style attribute.
