Parent post selector in edit post form not working correctly

Symptoms

A recent update to Forms broke the parent post select input when used on post edit forms, making it impossible to search for or update the parent.

Attempts to use the input will simply display “No results found”.

Workaround

The fix has been released, if you do not see the updates use the Check for Updates button in the custom Toolset installer page, or download from toolset.com/account/downloads
