带有YouTube视频的iframe - 辅助功能错误:通过ID引用其他元素的ARIA属性应该引用DOM中存在的元素

Question

我有一个包含Youtube视频的iframe,如下所示:

<iframe src="//www.youtube.com/embed/my-video" width="225" height="150"></iframe>

当我通过Chrome辅助功能审核运行网站时,我在iframe中收到以下错误:

[Severe] ARIA attributes which refer to other elements by ID should refer to elements which exist in the DOM (3)
See AX_ARIA_02 for more information.

知道如何解决这个问题吗？

====更新

我注意到了其他错误:

[Severe] Controls and media elements should have labels
See AX_TEXT_01 for more information.
<video class=?"video-stream html5-main-video" style=?"width:? 225px;? height:? 150px;? left:? 0px;? top:? -150px;? transform:? none;?">?</video>?

和

[Severe] Elements with ARIA roles must ensure required owned elements are present (3)
See AX_ARIA_08 for more information.
<div class=?"ytp-playlist-menu-items" role=?"menu">?</div>?
<div class=?"ytp-related-menu-items" role=?"menu">?</div>?
<div class=?"ytp-menu" role=?"menu" id=?"ytp-main-menu-id">?</div>?

据推测,Youtube视频播放器不符合ARIA标准吗？
