When editing large CSS files (3k+ lines) via the templating kit section in Admin Central, we are running into an issue where typing a few letters takes an unacceptably long time.
For example, if you tried to move the caret to the last line, after the click you would have to wait nearly a minute before it would show up. Then to type a single letter, you have to wait another minute and so forth.
We've tried this in multiple browsers (Chrome stable and unstable, Firefox, Safari) and we get the same terrible performance. It happens on deployed instances, as well as local development instances.
Is there an easy way to disable codemirror and just get a regular text area?
We are using Magnolia 4.5.2.
