No SCSS / SASS support on Developer Edition Inspector?

Most developers I know work with SASS. Like Chrome Inspector reads SASS source maps. Will this be built in?

There is some support for CSS source maps in Firefox DevTools.

The inspector’s rules view should show the line number in the original source / SASS file.

The style editor should show the original source / SASS file.

If you don’t see this, make sure “Enable Source Maps” is on in the options panel (click gear icon).

Here’s a demo page you can try:

Thank you for your reaction. In your example it indeed works, on my project it does not. I tried a couple things like disabling gzip and timestamp (after filename), but no result. I guess this is still under development.

I analysed this a bit further, maybe the cause of the problem is an invalid https certificate which I set up on my local development environment to simulate the production environment.
Chrome has no problems with it. I noticed this because a likewise project I have setup without https does use the source maps.

[EDIT] it is not the cause. Is there any debug method to track the cause? I use Zurb Foundation. Thx
