Page tree macro throwing an error when specified a non root page

Issue Summary

When a non-root page from a different space is added to the page tree macro, upon publishing the page, it throws an error " The selected root page could not be found".

Also at times, it results in the same error being shown but in a different language.

Steps to Reproduce

• Create a page and use the Page tree macro.
• Select the space to limit the results
• Put a non-root page in the macro config
• Publish the page.

It will throw the below error.

Expected Results

Should have shown the child pages from the page specified

Actual Results

The macro works when trying to specify a page in the same space, but throws an error when trying to specify a non-root page from a different space.

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available
