Tags <ins> and <del> are not preserved when added to allowedTags

[corinagum]

To Reproduce

const options = {
  allowedAttributes: {
    a: ['aria-label', 'href', 'name', 'rel', 'target', 'title'],
    img: ['alt', 'src']
  },
  allowedSchemes: ['data', 'http', 'https', 'ftp', 'mailto', 'sip', 'tel'],
  allowedTags: ['del', 'ins', 'etc...']
};
console.log(customMarkdownIt.render(sanitizeHTML('<ins>insert</ins> <del>delete</del>', options);

1. Run above code
2. Note result is <p>insert delete</p>

Expected behavior

<p><ins>insert</ins> <del>delete</del></p>

Describe the bug

Tags <ins> and <del> are filtered even when those tags are allowed to allowedTags.

customMarkdownIt is unrelated to this package. Please test again without that. I added those tags to the "should accept a custom list of allowed tags" test in the test suite and it worked fine.

Please specify what version of sanitize-html you're using.

I see you fixed your project issue. Closing this.

Hey sorry for the late reply, and for the confusion. Thought I did my due diligence and I was wrong. Thanks for taking a look.
