heading 2 becomes heading 1

[timvink]

While writing unit tests, I noticed that:

# one
### two
## three

Will lead to ## three becoming a <h1>. (see screenshot below).

Is that intended behaviour? I have not enabled strict_mode.

Thinking about this a bit more. Does it actually make sense to have two modes:

strict_mode: When set to True it will follow the headings order strictly. You must start writing documents from h1, and cannot skip headings (such as # title1\n### title2\n).

As in:

# title
### title 2
## title 3

Should always produce:

# 1. title
### 1.1.1 title 2
## 1.2 title 3

Or am I missing something?

   When I was writing the code, I didn't expect this to happen. This is indeed a bug.Please help me fix it.
   As for Strict Mode, my idea is that once the above happens, the number will stop from where the disorder has occurred. This applies to situations where you write something like something at the end of the article, rather than want to number.
