Accessibility: Inline frame without a text alternative

[kevinkidwell]

Describe the bug
When a video is embedded using an iFrame HTML element, you must add a title attribute that states the title of the video, if it is not present. This should be fixed by Content Owners. Example below of correctly formatted title attribute:

<iframe width="800" height="574" src="https://macaulaylibrary.org/asset/33501031/embed/800" frameborder="0" allowfullscreen style="width:800px;" **title="This is your title of the video"**></iframe>

Note that this also applies to any iFrames embedded that are not videos. We have a number of these on the site and they should also be fixed by Content Owners.
