Built-in macros not available to select

Steps to Reproduce

• Install Confluence 6.11.0 (also reproduced on other versions)
• Install ScriptRunner 5.4.26 (also tested on 5.4.36)
• Attempt to add any built-in macro to a page, such as Lock Content or Include Version

Expected Result

Macro appears in the macro list and is selectable, or shows when typing markup with curly brackets.

Actual Result

Macro does not appear.

Workaround

Disable any one of the built-in macros on the Script Macros page. All macros (except the one you just disabled) will now appear again when editing a page as expected. Enabling the disabled macro will cause it to appear again as expected.

Additional

The bug also affects other built-in macros, such as Page Info from the Page Info add-on.
