Thanks Tim! (I found a couple of other little things to fix, so I'll make some tweaks before landing).

> Source/WebCore/html/HTMLAttachmentElement.h:70
>      void parseAttribute(const QualifiedName&, const AtomicString&) final;

I also meant to remove the declaration of the `HTMLAttachmentElement(const QualifiedName&, Document&, const String& identifier);` constructor above — I'll do this before landing.

> Source/WebKit/UIProcess/Cocoa/PageClientImplCocoa.mm:53
> +#endif

Self nit - this should have an #else UNUSED_PARAM(identifier), otherwise the build would break with an unused variable if we were to somehow have ENABLE_ATTACHMENT_ELEMENT without WK_API_ENABLED.

> Source/WebKit/UIProcess/Cocoa/PageClientImplCocoa.mm:60
> +#endif

Ditto.

Rolled out in <https://trac.webkit.org/changeset/224544>

[Wenson Hsieh]

Upon further investigation, this API test runs into an existing bug related to text decorations — this is reproducible with the following simple layout test (run from within LayoutTests/editing/execCommand/)

<body contenteditable></body>
<script>
document.body.focus();
document.execCommand("InsertHTML", true, "<img src='../resources/abe.png'></img>");
document.execCommand("SelectAll");
document.execCommand("Underline");
document.execCommand("InsertText", true, "foo");
</script>

[Wenson Hsieh]

Re-landed with a tweaked API test in <https://trac.webkit.org/r224593>. I've investigated the debug assertion, and determined that it's a separate (and existing) issue that has nothing to do with attachments. See <https://bugs.webkit.org/show_bug.cgi?id=179431> for additional analysis, as well as several proposals for a fix.
