New description:

 The ability to add any HTML formatting to text in captions is very
 limited.

 - HTML markup can be added from the HTML editor as long as you don't
 switch to the visual editor and the markup does not contain any quotes.
 - Currently the visual editor removes any HTML tags from captions.

 To do:
 - Handle HTML in the caption text escaping/encoding it to pass through the
 shortcode matching regex.
 - Provide some way of adding HTML in the captions in the gallery -> image
 properties. (This may be limited to links only as they seem most needed).
 - Improve editing of caption text in the visual editor after inserting an
 image with caption or add third "popup button" to images that would
 add/remove captions directly without needing to open the uploader/gallery
 popup.

Comment:

 Replying to [comment:14 sushkov]:
 > @jeremyclarke has a point when says that image caption content should go
 between [caption] shortcode tags.

 Don't think changing the structure of the image caption shortcode is
 possible. This would break all plugins and themes that use it directly (we
 explicitly allow that in `img_caption_shortcode()` with the
 `'img_caption_shortcode'` filter).

 I rather see that as escaping all quotes or encoding the html string in
 caption="...", whichever works better. If we need to encode it, we can
 decode before running the `'img_caption_shortcode'` filter to keep it
 back-compat.
