Bug: Query Loop: Authors filter generates posts of only first selected author.

[adi3890]

While using guntenberg block Query Loop I found an issue that actual reslt in frontend doesnot match multiple authors selected in editor. Result is populated only on the basis of first author selected in Authors filter.

Steps to replicate.

• Drop a query loop in a any post
• Add Multiple Authors in Authors Filter, update the page.
• Visit frontend

Expected

• Posts should be generated as per selected Authors

Actual Result

• Posts generated only on the basis of first selected author in the list of authors filter

This PR handles multiple cases where author data can be passed in any data format

• array - array of author ids
• string - comma separated author ids
• integer - single author id.
