How can I directly instantiate a tuple-like enum variant within the bsn! macro?

Bevy 0.19.0-dev (the main branch as of 2026-05-07, 1dce255)

I recently started trying the bsn! macro. Is it not possible to directly instantiate a tuple-like enum variant within it? The following a() function fails to compile.

use bevy::{prelude::*, text::LineHeight};

// error[E0599]: no variant or associated item named `default_px` found for enum `LineHeight` in the current scope
fn a() -> impl Scene {
    bsn! {
        LineHeight::Px(50.0)
    }
}

// No error
fn b() -> impl Scene {
    bsn! {
        LineHeight::from(LineHeight::Px(50.0))
    }
}
