Post History

Thanks for reporting this issue, this should be fixed now (or once the deploy is completed, which should be a few minutes/seconds from now).

The issue was, that we weren't expecting HTML tags to be there, except for the code for some badges that appear sometimes and indicate the post type. However, MathJax added tags, which caused some of the rendering to fail ("flex box" is the name of the guilty tool).

The solution was to simply put all the text into an other HTML tag.
