LibWeb: Allow cloneNode() to clone elements with weird attributes We can't rely on Element.setAttribute() in cloneNode() since that will throw on weird attribute names. Instead, just follow the spec and copy attributes into cloned elements verbatim. This fixes a crash when loading the "issues" tab on GitHub repos. They are actually sending us unintentionally broken markup, but we should still support cloning it. :^) 2024-04-21 18:16:27 +02:00			`<script src="../include.js"></script>`
