This omits the normalization jodit applies to every other URL attribute: `isDangerousUrl` strips control bytes with `value.replace(/[\\u0000-\\u0020]+/g, '')` and lowercases the value before testing the scheme. Because the `href` check does neither, it is bypassed by three obfuscation classes, all confirmed firing on click against the shipped 4.12.30 build:\n\n1. Case variants: `JAVASCRIPT:`, `Javascript:`, `jaVaScRiPt:` (the check is case-sensitive).\n2. A leading C0 control byte, e.g. a `\\x01` prefix before lowercase `javascript:` (`trim()` does not remove bytes in the `\\x00`-`\\x08` / `\\x0e`-`\\x1f` range, but the browser strips a leading control byte before resolving the scheme).\n3. An embedded tab or newline inside the scheme, e.g. `java\\tscript:` or `java\\nscript:` (the browser strips tab/newline from a URL, but `indexOf('javascript')` sees the broken word and does not match).\n\nThe dangerous href survives `editor.value =` assignment and the on-change LazyWalker, persisting in the stored editor value.
