For M1 scope, we don't track changes happening via the Style Editor because it just replaces the stylesheet text with the updated stylesheet. This behaviour (replacing a stylesheet completely) also happens with hot-reloading and can cause previously tracked changes to become invalid. Reconciling between old and new stylesheets can be complex. We will not tackle it in M1 scope. However, as a fist step, we want to mitigate this issue by communicating as clear as possible to the user what's happening and why we're about to lose their tracked changes. The Changes panel should warn the user when a full stylesheet swap happens and give them a chance to copy/export their changes before resetting the panel.
