Inlay hints don't update when (default) features change

I noticed this issue when trying to implement a way for users to pick between tokio and async-std. Since the two don't function quite the same, I've had to write a small compatibility layer. Anyway, I have this bit of code:

#[cfg(feature = "async-std")]
#[inline]
pub fn lines_to_stream<R>(lines: futures::io::Lines<R>) -> futures::io::Lines<R> {
    lines
}

#[cfg(feature = "tokio")]
#[inline]
pub fn lines_to_stream<R>(
    lines: tokio::io::Lines<R>,
) -> tokio_stream::wrappers::LinesStream<R> {
    tokio_stream::wrappers::LinesStream::new(lines)
}

To test that both versions work side by side, I have this in my Cargo.toml:

[features]
#default = ["async-std"]
default = ["tokio-runtime"]
tokio-runtime = ["tokio", "tokio-stream"]

and I switch between the two defaults when I want to test one or the other. What I've noticed is that when I make the switch, most things behave as expected (the items with the now inactive #[cfg()]s are dimmed and vice versa for the ones that are now active, e.g.), but the inlay hints don't update to reflect the changes. A call to that lines_to_stream above, e.g. will keep showing LinesStream<...> even after switching from tokio-runtime to async-std, even though it should say Lines<...> at that point.

They are updated as soon as any edits are made to the file in which the inlay hint appears, but just like how the dimming of the inactive #[cfg()]s happen without active user involvement, it'd be nice if the inlay hint was updated, too.

Start by reproducing the issue by switching the default feature in Cargo.toml between async-std and tokio-runtime and observing the inlay hint at the lines_to_stream call. Done means the hint refreshes when the feature selection changes, without editing the file.
