Description

We use LinkeDOM with Lexical to export HTML from an EditorState on the backend.
The PR #204 introduced decodeURI on get href() and get download() to fix double encoding of already encoded characters but this causes every malformed URL to throw URIError.

For example, a LinkNode in Lexical can be anything, can also have % as URL. When it comes to converting the LinkNode to an HTMLAnchorElement via LinkeDOM, decodeURI throws and the whole HTML generation fails.

It's not a real problem, I can sanitize these URLs myself, but I wanted to report this anyway. Thanks a lot for everything, LinkeDOM is really fast!

Research direction

Reproduce the failure with a malformed URL such as %, then inspect cjs/html/anchor-element.js around line 19 and the change from PR #204. Verify that HTMLAnchorElement no longer aborts HTML generation for malformed URLs while the existing handling of already encoded characters remains intact.
