1. Load an XML file, for example one of the files inside an ODT or DOCX file. 2. Try to insert a string in a place where this is valid at the end using element.insertAdjacentHTML('beforeend', string) or element.innerHTML += string. 3a. If the string contains attributes with prefixes, such as '<manifest:file-entry manifest:full-path="Picture.jpg" manifest:media-type="image/jpg"/>' the insertion fails and a syntax error is thrown. 3b. If the strings does not contain attributes with prefixes, such as '<manifest:file-entry full-path="Picture.jpg" media-type="image/jpg"/>' the insertion succeeds (but the result is not what was hoped for). This does work in Firefox and Chrome and all existing child elements of element look just like the string in 3a, including prefixes.

Took test and changed it into JSFiddle: https://jsfiddle.net/L9uk0s2p/ *** Chrome Canary 115 *** Nothing in Console *** Safari Technology Preview 169 *** "<a class='gotoLine' href='#45:22'>45:22</a> SyntaxError: The string did not match the expected pattern." *** WebKit ToT (264046@main) *** [Minibrowser] "<a class='gotoLine' href='#45:22'>45:22</a> SyntaxError: The string did not match the expected pattern." *** Firefox Nightly 115 *** "<a class='gotoLine' href='#45:0'>45:0</a> SyntaxError: An invalid or illegal string was specified" _____________________________ From Comment 01, it seems that Firefox also changed the behavior since it was working fine.

This also happens for innerHTML. It seems like we don't implement https://html.spec.whatwg.org/#xml-fragment-parsing-algorithm correctly. Maybe Firefox changed their XML parser recently?

I took additional tests for this from Blink: https://src.chromium.org/viewvc/blink?view=revision&revision=191940 and now trying to merge in PR for fixing bug 66424.
