Psalm infers float|int when using template for positive-int|0

Given the following snippet https://psalm.dev/r/28b89bee3b

<?php

/**
 * @psalm-pure
 * @psalm-template T as positive-int|0
 * @psalm-param T $depth
 */
function recursiveFn(int $depth = 1): void {
    if ($depth > 1) {
        recursiveFn($depth - 1);
    }
}

Psalm reports:

ERROR: ArgumentTypeCoercion - 10:21 - Argument 1 of recursiveFn expects 0|positive-int, parent type float|int provided

Given the exactly the same snippet, except not using the template https://psalm.dev/r/412e21cd88

<?php

/**
 * @psalm-pure
 * @psalm-param positive-int|0 $depth
 */
function recursiveFn(int $depth = 1): void {
    if ($depth > 1) {
        recursiveFn($depth - 1);
    }
}

There are no (related) errors; presumably $depth is correctly identified as positive-int|0 here.
