Using a "/" in a Custom Jira field will prevent the content of the field to render in the Jira macro in Confluence

Issue Summary

In Confluence Cloud if you insert the Legacy Jira macro and try to display issues that include a custom field that includes a "/" (forward slash) in its name, the content of the field will not show in the Jira macro.

This is reproducible on Data Center: Not tested

Steps to Reproduce

1. Go to your Jira instance and create a customer field for one of your projects.
2. The custom filed name should include a "/" with no spaces in between the "/" and the words: Pre/Post operational work
3. Go to Confluence Cloud, select any page, and then insert the classic Jira macro.
4. Use JQL to locate the project, and then in the display options select the field with the "/" in its name.
5. Macro will render all the field contents correctly except for the contents of the field with the "/" in its name.

Expected Results

Regardless of the name of the custom fields, the contents should be displayed in the Macro

Actual Results

The Jira macro will not display the values for the custom fields with the "/" in its name.

Workaround

Go to Jira and remove the "/" from your custom field name

After changing the field in Jira, the macro must be manually updated to reflect the changed field without the slash due to CONFCLOUD-65930
