When updating an environment for a workspace, if the JSON body is malformed (for example, forgetting the comma at the end of a line), hitting the "Done" button closes the window as expected but the configuration is not saved. This can be frustrating when adding multiple lines to an environment with values that need to be copied and pasted from elsewhere.

The environment config panel should either:

1. Display syntax errors live while editing the JSON body, or
2. Display an error when trying to exit the panel with a malformed configuration

It would be a big help, thank you!
