iMessage Link Previews Truncating Head Content?

it seems that there is some ML going on to cut out the title of link previews in messages, is there official documentation on this?

for example, my site has this as its tag

<meta property="og:title" content="Orbits | The Circular Word Game" />

but it displays in link previews as

why is this? after some testing with different heads it seems to always filter out Orbits

What happens if you query the title with JS?

let titleContent = document.querySelector('meta[property="og:title"]')?.content;

I did some testing with a friend and it doesn't matter if its a - or a | or if it comes first or last, it typically filters out site names.
