Rust modules: f32 default values not respected

[bfops]

repro script:

echo 'Publishing module code:'

tee src/lib.rs <<EOF
use spacetimedb::{ReducerContext, Table};

#[spacetimedb::table(accessor = person, public)]
pub struct Person {
    name: String,
}

#[spacetimedb::reducer]
pub fn add(ctx: &ReducerContext, name: String) {
    ctx.db.person().insert(Person { name });
}
EOF
echo

echo 'Publishing module'
spacetime publish --delete-data -y
echo

echo 'Adding person'
spacetime call add Foo
echo

echo 'Current people:'
spacetime sql 'select * from person;'
echo

echo 'Updating module code:'
tee src/lib.rs <<EOF
use spacetimedb::{ReducerContext, Table};

#[spacetimedb::table(accessor = person, public)]
pub struct Person {
    name: String,
    #[default(123.4)]
    number: f32,
}

#[spacetimedb::reducer]
pub fn add(ctx: &ReducerContext, name: String) {
    ctx.db.person().insert(Person { name, number: 432.1 });
}
EOF

echo 'Publishing updated module'
spacetime publish -y
echo

echo 'Current people:'
spacetime sql 'select * from person;'
echo

The final output of this for me is:

 name  | number                            
-------+-----------------------------------
 "Foo" | -0.000000000000000000000015881868 

rather than the expected 123.4 value
