What change do you want to make?

Generate fewer warnings

How do you think the change should be implemented?

A new default behavior

Example code

<div></div>
<DIV></DIV>

What does the rule currently do for this code?

Currently, if allowed: ["DIV"] is configured, the rule will correctly allow <DIV></DIV>. However, <div></div> will be reported as an error because the matching is case-sensitive. This leads to false positives since HTML tags are, by specification, case-insensitive.

What will the rule do after it's changed?

After this change, the no-html rule will perform case-insensitive matching when checking HTML tag names against the allowed option list. This means that if allowed: ["DIV"] is configured, both <div></div> and <DIV></DIV> (and any other casing like <DiV>) will be correctly recognized as allowed and will not be reported as errors.
