+// This test supplements the web-platform-tests in:
+//
+// web-animations/interfaces/Animatable/animate-no-browsing-context.html
+//
+// Specifically, it covers the case where we have a running animation
+// targetting an element in a document without a browsing context.
+//
+// Currently the behavior in this case is not well-defined. For example,
+// if we were to simply take an element from such a document, and do:
+//
+// const xdoc = xhr.responseXML;
+// const div = xdoc.getElementById('test');
+// div.style.opacity = '0';
+// alert(getComputedStyle(div).opacity);
+//
+// We'd get '0' in Firefox and Edge, but an empty string in Chrome.
+//
+// However, if instead of using the style attribute, we set style in a <style>
+// element in *either* the document we're calling from *or* the XHR doc and
+// do the same we get '1' in Firefox and Edge, but an empty string in Chrome.
+//
+// That is, no browser appears to apply styles to elements in a document without
+// a browsing context unless the styles are defined using the style attribute,
+// and even then Chrome does not.
+//
+// There is some prose in CSSOM which says,
+//
+// Note: This means that even if obj is in a different document (e.g. one
+// fetched via XMLHttpRequest) it will still use the style rules associated
+// with the document that is associated with the global object on which
+// getComputedStyle() was invoked to compute the CSS declaration block.[1]
+//
+// However, this text has been around since at least 2013 and does not appear
+// to be implemented.
+//
+// As a result, it's not really possible to write a cross-browser test for the
+// behavior for animations in this context since it's not clear what the result
+// should be. That said, we still want to exercise this particular code path so
+// we make this case a Mozilla-specific test. The other similar tests cases for
+// which the behavior is well-defined are covered by web-platform-tests.
