Hello,

Do you know who I can contact regarding the Markdown Editor found on this page: https://jbt.github.io/markdown-editor/ ?

The editor does not correctly display the results for example 51: (Because I am limited to two links, please see the link in the code section below.)

In the example, the resulting display should be an H1. Instead, it is plain text.

Here's my editor session: 
https://jbt.github.io/markdown-editor/#jZFNasNADIX3OsWDLAqhsZNCNoYs0ybQ7nqBcazYgycjd37quKfv2GmaRShUMAyIp6dP0gwvOuxiiTfl2kp6i+2Z3UF7Jtqe1akzjPWqQBNC54s8r3VoYpn9fAc55fXxlM/4Il2sV6iEPawE9OJadE46dmZAyQcVPSM06fE5wDcSTZXyUBa7VUb0LIJ5qRyV6mtOmxREtP9VGpEWRrejh/ap0EgPbSfHSvvOqKEgmuFqg8mG6JXDg0dwA6LXtoZCpXyTKn1gVUGOkwN/RGXgdW3vSBYpks97UqlSPhmOfTQBCaJ3khyDSIb9lBgHH+d5yv5CZxzFJPSEMuLe89LeBk4tQlKY4RF8PcNyWqkv8O9rLG+jXBa6uWz1llxcg74B

Here’s the code from the Markdown Editor:

# GitHub Markdown Exercise
Example 51: https://github.github.com/gfm/#example-51 does not work properly because the text should be an H1.
Foo bar

baz
It should look like this below in the display:
Foo bar baz
Let's try using a dash instead of the equal sign.
Foo bar

baz
The above result is wrong too. It is not an H2.
It should look like the following:
Foo bar baz
Interestingly, example 50 works:  https://github.github.com/gfm/#example-50
Foo bar
Foo bar

I hope this information is helpful.
