html <dialog> elements ignore 'closedby'

[egnrse]

What happened?

html dialog elements (opened modal) seem to always use closedby=closerequest and ignore any/none.

eg. I can't close a modal dialog element with closedby="any" by clicking somewhere else on the screen. (This is working on firefox (150.0.3) / chrome (148.0.7778.167). )

See a code example below:

<button onclick="document.getElementById('song-details')?.showModal()">Details</button>
<dialog id="song-details" closedby="any"> <!-- the any here gets ignored -->
	<h2 id="title">title</h2>
	<p id="test">test</p>
	<button onclick="document.getElementById('song-details')?.close()">Close</button>
</dialog>

Reproducible?

• I have checked that this issue cannot be reproduced on Mozilla Firefox.
