The first image in this little gallery is a case in point: https://misterneutron.com/FBlongcaptions
On a big desktop monitor, no problem. On a typical 1024x768 laptop, however, the image disappears off-screen entirely. Ditto for a smartphone.
The results on an iPad are a bit stranger. I don't have one, but using the Chrome developer's toolbar, I can see what it looks like, and an actual iPad user has confirmed the result. If the iPad is held in portrait mode, the display is OK, though if the text is long enough, it's not all displayed. But in landscape mode, the image disappears.
At the moment, I'm not sure what I would want the script to do with this kind of prose overload, but having the image disappear completely, along with the navigation, is certainly not optimal!
ETA: On an iPad in portrait mode, in some galleries the caption for one image is even being displayed on other images. I'll post back when I can put together a demo of that effect.
