Log Message:
-----------
Document named properties should not filter object and embed elements by
exposedness
https://bugs.webkit.org/show_bug.cgi?id=322330
Reviewed by Chris Dumez.
The HTML specification's "exposed" concept, which no engine implemented
consistently, is being removed: https://github.com/whatwg/html/issues/12787
WebKit applied isExposed() when resolving a name but not when enumerating
supported property names, so Object.getOwnPropertyNames(document) could
report a name that resolved to undefined. Stop consulting it, matching
Gecko. Two behavior changes: an object or embed element nested in an
object element with the same name or id now matches alongside its
ancestor, so lookup returns an HTMLCollection rather than the innermost
element; and an object element with object or embed descendants is now
reachable by its name and id.
