Code field instantiation issue when used in other tabs

[aaronbushnell]

Bug description

There's currently an issue with the code field when you use it in a tab that isn't the primary one. Once you click on the tab that has the code field it appears empty. Focusing into the field renders the content but it's superimposed on the line numbers.

How to reproduce

1. Create a Code field, but place it into a tab outside of "Main"
2. Begin creating a new entry and go to the tab that contains your field
3. Save some content into the field
4. Refresh and go to the tab that contains your Code field
