+Subject: [PATCH] extensionSystem: Disable extension before unloading
+ stylesheet
+
+Removing a stylesheet from the theme will trigger a style update. There's
+little point in updating the extension actors that are about to be destroyed
+(hopefully), so call the extension's disable() function first.
