Cannot go to definition of tuple struct at constructor invocation

[doxxx]

Given the following:

struct Foo(u32);

struct Baz {}

fn stuff() {
    let x = Foo(1);
    let y = Baz {};
}

I cannot ctrl-click Foo in the stuff function, but I can ctrl-click Baz. The syntax coloring seems to imply that the Foo constructor is being recognized as a function invocation.
