User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0 Build ID: 20170307144106 Steps to reproduce: 1. Set up a directory with an html file + sass stylesheet, with main.css linked into index.html: . ├── index.html ├── main.css ├── main.css.map └── scss └── main.scss 2. Start sass (or similar) watching for changes to scss/main.scss and regenerating main.css and main.css.map accordingly. 3. View index.html in Firefox through the filesystem (file://) 4. Open up source-mapped sass file in the style editor 5. Make a change and save it Actual results: Firefox correctly live-reloaded the rendered page to reflect the changes, then after about a second, reverted the changes in the style editor without updating the page. Leaving me with my changes reflected in the rendered page, but the unchanged scss in the style editor. Undoing brought back my changes, putting the style editor back in sync with the page. Expected results: Firefox should not revert changes after saving.

The style editor calls the sheet actor's update method: https://dxr.mozilla.org/mozilla-central/rev/f9a5e9ed62103c84e4cde915f4d08f1ce71be83e/devtools/server/actors/stylesheets.js#715 However, this doesn't clear out the existing source map info, so eventually the style editor gets stale text for the original source. It's possible to clear the source maps in |update| but I wonder what effect that will have when, say, as-authored editing a rule. Though probably that is already kind of broken when source maps are present.
Not only did that not work, it's also too complicated - it seems to suffice to set _isUpdating in updateLinkedStyleSheet
