Change Details

I just noticed this huge blob being included on every page view of en.wikipedia.org, test2.wikipedia.org and presumably lots of other wikis as well. This wasn't there not so long ago, so either the extension regressed or it wasn't installed or enabled in this way before. This is will likely impact page render time due to this configuration being inside the `<head>` and thus slows down retrieval of more important things (like stylesheets and article content). With the goal of trying to squeeze the first stylesheet and above-the-fold content into 12KB, we can't give 5KB of that just for CodeMirror configuration. (T127328) This configuration should be removed from the default output and moved to a DataModule. Given VisualEditor supports a plugin list with module names, this shouldn't pose any problem.
