XF 2.2 Spoilered images are not unfuzzing upon being clicked.

[The Proctor]

As the title says; some of my users (and myself) cannot click on spoilered images. Nothing happens when they are clicked. They do not de-censor themselves. However, quoting them or saving them shows the image as normal.

Does it happen in a default style with all third party add-ons disabled and all custom javascript removed?
