Double Space between `pub &` when preceeded by long attribute

[jonasbb]

Describe the bug

Formatting this code places two spaces between pub and &.

struct X<'a>(
    #[X(X = "_________________________________________________________________________")]
    pub  &'a u32,
    // ^^
);

Expected behavior

The usual formatting is pub &'a u32 (single space). I would expect rustfmt to stay consistent. Removing the attribute, shortening it, or turning it into a comment all lead to the single space formatting.
