Footnote <table>s are nested in a <p> tag

Semantically <p> tags should not contain <table>.

There's quite a few issues opened here to do with <p> tags. Long story short Franklin is something on top of the Base.Markdown markdown to html conversion which is faulty. Franklin then bends over backwards to try to avoid having unclosed <p> blocks (which it doesn't always manage to do). The logic that does this is complicated and hard to maintain, adding extra cases to try to avoid what you flagged is not the right path.

The future version which can be previewed here https://github.com/tlienart/Xranklin.jl (though not recommended for use atm, it's work ongoing) has its own markdown to HTML converter; it's not perfect but it's better by avoiding going through the Base converter; and since it constructs the HTML in a saner manner, there are fewer issues though there will likely still be some. I've put a fair bit of effort into trying to limit the number of cases where tags are unclosed (because it's important for things like minifiers) and to keep the HTML logic correct, this is not something that's trivial to do for a number of reasons however (unless you build the HTML tree which is not what I wanted to do for a bunch of reasons) and in order not to have complicated and hard to maintain logic in the code, there will definitely be cases where the generated HTML will be properly rendered by any standard browser and yet won't be fully semantically correct.

The case you flagged (table within a paragraph) is one of the few basic erroneous cases that will go away though.

Hope that makes sense!

That's OK, I've already came up with a work around specifically for the footnotes.
