POST_PARENT_TITLE placeholder doesn’t work in Forms notification emails

Symptoms

The %%POST_PARENT_TITLE%% or %%POST_PARENT_LINK%% placeholders in Toolset form notifications are not replaced when sending emails.

This happens for posts in relationships created with the new (Types 3.0+) implementation of Post Relationships or when more than one parent is set for the post created or edited by the Form.

Workaround

This is expected. Those placeholders and parent attributes are only expected to work in legacy relationships and only if only one parent post is available.

We will consider adding placeholders in the future that are compatible with the current relationship implementation of Types.
