Meta tags are rendered as if it were one page only

[S-Groening]

I don't know from looking at the docs, if it's supposed to be treated like this, but when including second.md into first.md, the meta tags of second.md gets rendered as visible text surrounded by line dividers in a way, that makes me think the sources are not being treated individually for it to then be combined in HTML. I might be ignorant to how mkDocs works internally, but I'd rather prefer each source to be treated individually before being combined in the correct order, according to include tags, if this makes any sense 😊

My issue specifically comes into play when using a homegrown macro to read through the page meta, extracting authors, but the way the plugin works, the including page's meta gets copied to the included pages and the page meta also ends up in the HTML, even if they're all treated as comments in the individual markdown renderings...

Is there any way to keep the last thing from happening? Then maybe I can invent some way of making the authors macro work as desired...

Best regards and thanks for a nifty plugin!

Can confirm it's counterintuitive if you have meta sections as referenced here for blog purposes or other https://www.mkdocs.org/user-guide/writing-your-docs/#yaml-style-meta-data. You expect it will read the .md file and ignore any meta/context

When rendering to html the result will look something like this
