(This issue for chromium: <a href="https://bugs.chromium.org/p/chromium/issues/detail?id=693037">https://bugs.chromium.org/p/chromium/issues/detail?id=693037</a> )
Test case: <a href="http://software.hixie.ch/utilities/js/live-dom-viewer/saved/4892">http://software.hixie.ch/utilities/js/live-dom-viewer/saved/4892</a>
HTML standard:
[[
The following content attributes must not be specified and do not apply to the element: ... readonly, ...
]]
<a href="https://html.spec.whatwg.org/#range-state-(type=range">https://html.spec.whatwg.org/#range-state-(type=range</a>)
In Gecko and Edge, readonly does not apply as per spec.
I think the WebKit/Chromium is confusing UI.
