1402382 - stylesheet actor requests original source even when provided by source map

Status: RESOLVED FIXED

(DevTools :: Style Editor, defect, P3)

Description

[Tom Tromey :tromey]

The stylesheet actor can request an original source by trying to fetch
its URL, even when the source is available in the source map itself.
See https://github.com/mozilla/source-map/issues/211 for details.
It links to a reproducer: https://github.com/glen-84/ff-sourcemaps-issue

This will necessarily be fixed once bug 1179820 is done.
However it would be nice to verify the fix, perhaps by landing a test
case here.

I think the basic issue is that the stylesheet actor passes in the full URL;
but the source map library won't accept this when the sourceRoot is relative.
https://github.com/mozilla/source-map/pull/282 should fix that.

I think I'll land a new source-map bundle here in the interim.
This will fix the problem and hedge against not converting the inspector.

Actually, I'll just file a new bug for landing the bundle.
At some point we may still want a test here.

There's a test upstream and the inspector is using client-side source maps now, so closing.
