    11I think it's because the `wpeditimage` TinyMCE plugin uses `tinymce.dom.DOMUtils.setAttribs` which just recursively calls `tinymce.dom.DOMUtils.setAttrib` which accepts 3 params, and about the `value` one:
    2 > Value to set on the attribute - if this value is falsy like null, 0 or '' it will remove the attribute instead.
     2> Value to set on the attribute - if this value is falsy like null, 0 or "" it will remove the attribute instead.

    44So when `wp.media` passes an empty alt attribute, TinyMCE just strips it out. It makes sense to remove empty HTML attributes, with the notable exception of the `alt` attribute. While WordPress should ensure this doesn't happen and try to find a way to re-add the empty alt attribute when appropriate, maybe this should be reported upstream too.
