pseudocode in a wikipedia page, like all text, gets moved around by images whose placement has changed and other "prettifying" that wikiwand does to wikipedia pages. This makes it harder to read in some cases. For example, at this page: http://www.wikiwand.com/en/Bellman%E2%80%93Ford_algorithm#Algorithm. As you can see, the shifting around of the pseudocode text is not desired. Maybe make pseudocode blocks special in that nothing gets put over them or causes them to look different than usual.
