fix(view): InvalidClosingTag should ignore commented out code attributes

[erikaraujo]

This PR introduces a failing test for #1287.

The issue seems to be a combination of the code being commented out and the /svg part of the xmlns attribute of the svg tag in the following snippet:

<h1>
    <!-- <svg xmlns="http://www.w3.org/2000/svg">
    </svg> -->
</h1>

I believe this was fixed with #1289 ?

Indeed, this was fixed. Gonna merge the PR though because an additional test is always good
