Template:Imagestacks on Commons broken
Closed, ResolvedPublicBUG REPORT

Description

Template:Imagestack on Commons is used to scroll through sets of images. (Typically these are medical images like MRI scans.)

So the desired behavior is, that only one image is shown, and one can click or scroll to the one before or after.

Now it is broken, and all images are shown below each other. This was probably caused by changes in the Javascript or CSS.

This screenshot suggests, the problem is missing Javascript.
(Other users have confirmed the problem. So this is not just in my browser.)

I do not know since when the problem exists, but I know that it still worked on June 21.

This is because the HTML for the images changed.

And Interface admin on Commons can fix this by changing https://commons.wikimedia.org/wiki/MediaWiki:Gadget-ImageStack.js#L-34 from .ImageStackUnits div.center to figure

So the fix was adapting a find in jQuery, after the HTML had been changed. Could someone also link that HTML change? I suppose there must be some protocol to check depending JS before changing the HTML. It would be useful to figure out what went wrong.

Nothing went wrong. The change was communicated, but it is very difficult to know all the things that depend on this exact structure. Stuff falls through the cracks, especially with Commons not having a ton of js/css capable editors any longer.

Theres also about 6 gadgets still depending on jquery ui which has been deprecated for like 6 years now.
