Confusing error when using future wrapper

[Disasm]

(Playground)

use std::future::Future;
use std::task::{Context, Poll};
use std::pin::Pin;

pub struct AnyFuture<F> {
    inner: F,
}

impl<F: Future> Future for AnyFuture<F> {
    type Output = F::Output;

    fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output> {
        self.inner.poll(cx)
    }
}

Error:

error[E0599]: no method named `poll` found for type `F` in the current scope
  --> src/main.rs:13:20
   |
13 |         self.inner.poll(cx)
   |                    ^^^^ method not found in `F`
   |
   = help: items from traits can only be used if the type parameter is bounded by the trait
help: the following trait defines an item `poll`, perhaps you need to restrict type parameter `F` with it:

9  | impl<F: std::future::Future + Future> Future for AnyFuture<F> {
   |      ^^^^^^^^^^^^^^^^^^^^^^^^

error: aborting due to previous error

Of course, adding the suggested trait bound does not help.

Appears to be the same case as #57994

@memoryruins, indeed. Also works with Rc<Self>, Box<Self> and so on.

pub trait TestTrait {
    fn test(self: Box<Self>);
}

pub struct Wrapper<T> {
    inner: T,
}

impl<T: TestTrait> TestTrait for Wrapper<T> {
    fn test(self: Box<Self>) {
        self.inner.test()
    }
}
