Disabling the cascade options in the custom field doesn't get any effect in new issue view

Issue Summary

We have a custom cascading field called Tribe & Squad which we use heavily for our metrics reporting. There are some Squad options that we've disabled in the custom field default context and although those options are correctly disabled in the Jira Old View, however, they remain enabled in the JIRA New View.

Steps to Reproduce

1. Create a cascade custom field.
2. Add options in the custom field and in each option add cascade options.
3. Link this custom field with a screen.
4. Disable any cascade option.
5. Open the issue view using the new issue view.
6. Check the available cascade options in the custom field.

Expected Results

When selecting the custom field options and checking the cascade options, the cascade options that I've disabled is not appearing on the drop-down list using the new issue view.

Actual Results

When selecting the custom field options and checking the cascade options, the cascade options that I've disabled are still appearing on the drop-down list using the new issue view.

Workaround

Switch to the old issue view.
