This is a follow up of the previously raised PR. That one was agreed to be merged, but had merge conflicts and seems like the author of the PR has stopped maintaining it.
The original description was:
"The attribute for title and caption are now configurable via the option array. A caption is usful to give an additional image description or provide proper attribution. This includes the XSS fix from #268"
I like the idea of having an ability to add an optional comment to the photo, as for example in my gallery I'm storing comments in JPEG's tags. They can be multi-line and are not necessarily suitable for the main title. In the original version, the title doesn't support multiple lines allowing the text to overflow.
JS is not my specialty, I just replicated the original changes, so happy to incorporate corrections/suggestions if any
