Full volume PDFs mistakenly linked as frontmatter

Problem Description

When have we started linking full volume PDFs to frontmatter, instead of to the volume's <meta> block? Examples:

• https://aclanthology.org/2021.nejlt-1.0/
• https://aclanthology.org/2018.ijclclp-1.0/
• https://aclanthology.org/2019.ijclclp-1.0/
• https://aclanthology.org/2020.ijclclp-1.0/
• https://aclanthology.org/2021.ijclclp-1.0/
• https://aclanthology.org/2017.tal-1.0/
• https://aclanthology.org/2019.tal-1.0/
• https://aclanthology.org/2020.tal-1.0/
• https://aclanthology.org/2021.tal-1.0/
• ~https://aclanthology.org/2023.acl-long.0/~ (sorry, got ahead of myself here, this is correct)

IMO none of these should be <frontmatter>. I feel we're doing something fundamentally wrong here?

Example for a correct use of the frontmatter block: https://aclanthology.org/volumes/2023.acl-demo/
