MD025 Error when using front_matter_title and h1

Hi, when using title in a YAML frontmatter (aka metadata block) the first heading h1 throws a linting error for rules MD025 and MD043. When omitting h1, the top heading h2 throws error MD043.

front_matter_title: "^\\s*title\\s*[:=]" is set for MD025 and for MD041. Rule MD041 is working fine, as it throws no error. (Just in case: Setting front_matter_title: "" for MD025 in my .markdownlint.yaml is not changing anything.)

NB: I have read both the Readme and the Rules.md doc, and I had a look at known issues.

The expected behavior would be a) to be able to use both a frontmatter title block and a # First Heading together, or b) to be able to omit the # First Heading when using title inside a frontmatter.

As I found no solution to this, it might be a bug in the linter specs – or this (intended?) limitation should at least be (better) described in the docs.

The issue has also been described here: https://github.com/microsoft/vscode-docs-authoring/pull/269

OK, it seems we agree this scenario should generate an MD025 error due to two top-level headings: https://dlaa.me/markdownlint/#%25m--- title%3A "Hello world" --- %23 Top level heading

Switching the second of those to a second-level heading generates no errors: https://dlaa.me/markdownlint/#%25m--- title%3A "Hello world" --- %23%23 Second level heading

Is that not what you are seeing?

It sounds like you are describing this scenario in which case it sounds like you are seeing the expected behavior: https://github.com/DavidAnson/markdownlint/blob/main/test/front-matter-title-h1.md

If the YAML front matter includes a title, then the H1 element is redundant - as would be a top-level Markdown heading.

If your scenario is different, please provide example Markdown and explain what you expect.
