Coy theme shadow doesn't correctly wrap around floats.

Years ago I had turned off the Coy theme shadow as we discussed in #894, but I had forgotten exactly why. (I had thought it only had to do with scrollbars in generated PDFs in #859.) So when I updated to the latest Prism a few days ago and published my entire software development course, I left the Coy theme shadow on.

Now I see that the Coy theme shadow is broken when wrapping around flows. Here are a couple of examples:

• https://www.globalmentor.com/courses/softdev/unit-tests (Look for the figure with the caption “Testing Math.abs(int).”)
• https://www.globalmentor.com/courses/softdev/surf (Look in the section “URF, SURF, and TURF”.)

If you need, you can include the workaround in your project CSS, if you want the maintain the shadows.

I really think you need to document the differences among the themes, the bugs each have, and the workarounds, though. It’s not good to have people happily download what according to the site is a wonderful, beautiful, perfect thing; and then halfway through a project find out it breaks their layout because they weren’t informed.

It seems like Coy is the only theme that exhibits this behavior. All other themes work as intended in that the pre doesn’t overlap with other elements.

The cause is that the overflow of the pre is set to visible. Any other overflow value will fix the bug and will make Coy behave like all other themes but it also breaks Coy’s design completely.

So I tried to rewrite the Coy theme to not use overflow: visible on the pre but couldn’t do it. My problem was is overflow: visible is the only overflow value that allows you to draw outside the pre. Without it, the shadows aren’t possible, at least for me.

I’ll make a PR with my first fix (clear: both). By far not perfect but I hope it’ll solve your problem.
