🐛 Bug Report

The article titles are behaving differently than before and in not consistent ways.

Have you read the Contributing Guidelines on issues?

Yes

To Reproduce

1. I have a site where an article has the following front-matter section:

---
id: azuread_setup
title: Azure AD Configuration Setup
hide_title: true
hide_table_of_contents: false
sidebar_label: Azure AD Configuration Setup
description: Azure AD Configuration Setup
keywords:
  - Application
  - Web Server
  - Requirements
---

followed by a header 1 title
# My Header

Expected behavior

I expect the front-matter Title to be hidden and the string My Header to be displayed as a title

Actual Behavior

My Header title is hidden as well.
Also if i have instead of # My Header a second level header immediately after the front-matter section, i see the ID displayed as a title.
