TestCase::assertEqualsCanonicalizing() not converts and sorts data recursively

[WinterSilence]

Q	A
PHPUnit version	>7.5.*
PHP version	>7.0.*
Installation Method	Composer

Summary

Assertion method TestCase::assertEqualsCanonicalizing():

1. not converts/sorts data recursively
2. undocumented and invalid comparing object's classes
3. use algorithm same to assertEquals() instead assertEqualsWithDelta() to compare float properties

Current behavior

undocumented and not usable to tests

How to reproduce

$this->assertEqualsCanonicalizing([(object) ['a' => 1, 'b' => 1]], [(object) ['b' => 1, 'a' => 1]])

class Dummy
{
}

$expected = new Dummy();
$expected->a = 1;
$expected->b = 0.333;

$actual = new Dummy();
$actual->b = 0.33333;
$actual->a = 1;
$this->assertEqualsCanonicalizing($expected, $actual);

class Parent
{
    public $a = 'Foo';
}

class Child extend Parent
{
}

$this->assertEqualsCanonicalizing(new Parent(), new Child());

Epic fail...

Expected behavior

inverse of current behavior

@WinterSilence is it still an issue for you? I cannot reproduce it from the examples here in PHPUnit 10 (lowest supported, currently).
