Selected syntax/language doesn't get saved in code field inside Bard

[joshuablum]

Bug description

When you have a code field as a set inside of a bard field and select a different syntax/language than the default and save it, it doesn't save the selection but jumps back to the default. Works fine with a non-bard code field.

How to reproduce

1. Create a bard field
2. Add a code field set to it
3. Select a default mode like PHP
4. Edit an entry with the updated blueprint and select a different language than the default, like Markdown
5. Save the entry
6. See that the language mode is PHP instead of Markdown
