editing the config:

viewing details of this config:

Describe what you expected to happen

the code highlighting should display as what we defined, or we can choose the code highlighting style when re-editing it.

The latest version's edit page have solve this problem, but the details page still have this problem:

I dont know why editing page is using inputbox to show those configs(and the input box is not editable), but, anyway, the configs should be hilighted correctly as the editing page do.
