Expand the amount of space that an image caption can use.
Currently when clicking on an image to expand it, any caption text is only displayed on one line above the image and longer captions are truncated with '...'
Frequently I click the first image in an article and want to browse through them using the thumbnails at the bottom, but it is more difficult if one of the images has a longer caption text. I have to close the expanded view, scroll through the article to find the image I was looking at, read the caption and then reopen the expanded view to continue browsing the thumbnails.
It would be a much better experience if we could hover over the truncated caption to reveal the rest of the text, or if the caption was just given more space (but this would make the image smaller).
