I'm searching for a resolution which can add title attribute (title="") to a WordPress gallery. Now, the code looks like this:

<img width="400" height="400" src="http://example.com/wp-content/uploads/2017/03/myimage-400x400.jpg" class="attachment-thumbnail size-thumbnail" alt="image alt desc">

I specified the title in the media editor, but the attribute is not showing in the image tag.
