Axum 0.8: no method named into_response found for struct PreEscaped

[d6y]

Hello! I've been updating a project from Axum 0.7 to 0.8 and I've run into:

no method named `into_response` found for struct `PreEscaped`

when using html! and converting to an Axum response.

I've created an example that compiles under Axum 0.7:
https://github.com/d6y/axum-maud-into-example/blob/main/src/main.rs

I've created the failing change as:
d6y/axum-maud-into-example#1

It feels like I've missed something basic: any clues much appreciated.

Make sure you've included the axum feature for maud in your Cargo.toml
