"“Previously, we added a change to not load JavaScript on edit pages when editing Wikia.js/Monobook.js/Common.js, so that users can fix errors in their code that would otherwise stop the editor from loading. This has now been extended to a user's global.js/wikia.js/monobook.js/common.js.”"

Okay, I see why this has been done for wikia.js and monobook.js... but this ain't helpful to those that have customized the edit page using JavaScript in global.js. Please re-think that modification!
