hovering over constant containing function pointers shows internal constants

[antonilol]

rust-analyzer version: rust-analyzer version: 0.4.1943-standalone

rustc version: rustc 1.77.0 (aedd173a2 2024-03-17)

editor or extension: code oss, arch linux

relevant settings: None

code snippet to reproduce:

pub const FN: &[fn(usize, usize) -> usize] = &[or, xor];

pub fn or(a: usize, b: usize) -> usize {
    a | b
}

pub fn xor(a: usize, b: usize) -> usize {
    a ^ b
}

hovering over the FN constant shows

pub const FN: &[fn(usize, usize) -> usize] = &[0x3E8 as fn(usize, usize) -> usize, 0x3E9 as fn(usize, usize) -> usize]

which is not very useful (the internal constants and repeating the type)

	TyKind::Function(_) | TyKind::Raw(_, _) => {
	let it = u128::from_le_bytes(pad16(b, false));
	write!(f, "{:#X} as ", it)?;
	ty.hir_fmt(f)
	}

It seems like an address or something else.
