PHP with tidy and custom-tags

[franck-paul]

Description

The following code:

<?php
$str = '<custom-html-element>test</custom-html-element>';

$config = [
	'custom-tags' => 'blocklevel',
];

$tidy = new \tidy();
$tidy->parseString($str, $config, 'utf8');
$tidy->cleanRepair();

$str = (string) $tidy->value;

var_dump($str);	// should be <custom-html-element>test</custom-html-element>

Resulted in this output:

test

But I expected this output instead:

<custom-html-element>test</custom-html-element>

I'll take a look. Enum translation appears to be broken.
As a workaround for now you can use 'custom-tags' => 1,

On first sight the following would work, but have to double check (and probably add support for the IS_LONG case):
