`<gallery mode="packed-overlay">` or hover in combination with long descriptions makes impossible to access to the images featured in the gallery, since they cover the whole image. This is bad in terms of UI, but it might even have legal implications because clicking the image is the only way to check its license, attribution, etc. Original report: https://ca.wikipedia.org/wiki/Topic:Sdwh62gxhyoovqnx (PS: It is unclear where <gallery> bugs should be filed, and they can be found in different places)
