Jira allows creating an issue with a disabled value on a custom field

Issue Summary

It is possible to create an issue with a disabled value on a custom field, by setting the value directly on the URL.

Steps to Reproduce

1. Create a custom field of type Select list (single choice).
2. Add two values to the custom field, where one is going to be disabled.
3. Add the custom field to the Create Screen.
4. Create a URL for the Create Issue screen, such as: https://<JIRA_URL>/secure/CreateIssueDetails!init.jspa?pid=10043&issuetype=14&customfield_10121=12140
   1. The id 12140 is the disabled value.
5. The issue will be created with the disabled value.
   1. Once you edit the custom field's value, the disabled one no longer appears in the drop-down list.

Expected Results

It should not be possible to populate custom fields with disabled values.

Actual Results

The Issue is created with a disabled value on the custom field.
