mb_convert_kana does not work on HK combination in PHP8.2.26

[cjayalmontecm]

Description

The code below works fine on older version(PHP 8.1.13, 8.0.30, 7.4.33), but returns Fatal error: Uncaught ValueError: mb_convert_kana(): Argument #2 ($mode) must not combine 'H' and 'K' flags in PHP 8.2.26.

The following code:

<?php
$valueStr = "ｶﾀｶﾅ ﾛﾏﾝﾁ 123";
$valueStr = mb_convert_kana($valueStr, 'rnaKVH', 'UTF-8');
echo $valueStr;

Resulted in this output:

// for PHP 8.1.13, 8.0.30, 7.4.33
カタカナ ロマンチ 123

// for PHP 8.2.26
Fatal error: Uncaught ValueError: mb_convert_kana(): Argument #2 ($mode) must not combine 'H' and 'K' flag

But I expected this output instead:

// for PHP 8.1.13, 8.0.30, 7.4.33
カタカナ ロマンチ 123

// for PHP 8.2.26
カタカナ ロマンチ 123

This is correct since H and K are flags for different operating modes.
