Rustdoc: odd wrapping in code blocks

Link to docs: https://doc.rust-lang.org/nightly/std/borrow/trait.Borrow.html
How it looks on my machine:

Notice the space before {. Also, that indentation: where is seemingly indented by two spaces, while fn is indented by four. However, if I copy the code and paste here, it looks normal:

pub trait Borrow<Borrowed> where Borrowed: ?Sized {
    fn borrow(&self) -> &Borrowed;
}

I'm in the process of modifying rustdoc's formatting to match the fmt-rfcs for where clauses and function definitions. The indentation of the top-level where clause should be modified by this change, but it looks like I still need to look into why that's getting an extra space before that one curly braace. For reference, here's what it looks like on my local rustdoc:

[QuietMisdreavus]

Note to self: This is because item_trait in src/librustdoc/html/render.rs prints a space after the leading where clause, regardless of whether it exists. But if it exists, then the where clause itself prints a newline. The space is there so that traits without where clauses can put their opening brace on the same line as the trait name.

It looks like the pre blocks on top of struct/trait pages now use where with display: block; which I think was an unintended change (intended only for method items).
