Comment (by afercia):

 @jrf thanks! I think @swissspidy has more context but I'll try to describe
 what I see in the patch the best I can.
 We need to add a title attribute with the video title to the HTML returned
 from an oembed provider response. The patch already checks if the oembed
 is a video.
 After that, it uses the following regex to search for an existing title
 attribute in the returned HTML:
 `$pattern        = '/title\=[\"|\\\']{1}([^\"\\\']*)[\"|\\\']{1}/i';`

 that could match any title attribute in any element in the returned HTML.
 Instead, we need to search for a match only within the `<iframe ...>` HTML
 tag, if any.
