The different fails here are a regression (see: https://wpt.fyi/results/html/semantics/forms/the-input-element/show-picker-disabled-readonly.html?label=experimental&label=master&aligned) 

Seems like the test expects a different error for readonly, based on the input type.

Firefox's implementation might be relevant here: https://phabricator.services.mozilla.com/D142754#change-NirQH5Dh8sEo, since it's the only one implementing this correctly.

Seems like the spec is consistent with Firefox as well: https://html.spec.whatwg.org/multipage/input.html#dom-input-showpicker

I found the more exact bit that describes on which elements the readonly attribute applies:

Can you remove the "on supported types" bits? 

I filed bug 240343 to fix the readonly supported types.

showPicker() to be consistent with other messages.

The title needs updating too, both in LayoutTests/imported/w3c/ChangeLog and Source/WebCore/ChangeLog
