Since the page contains an <h1> tag (the title of the issue), the main
headings of this file should be level 2 headings.
We're removing the "How" section in the flaky specs template for
simplicity (and because we usually don't use this template at all).
Note that MDL reports that the first heading should be a level 1
heading, but, as mentioned earlier, this doesn't make sense in the
context of a github issue. We'll probably exclude these files from MDL
checks in order to avoid this issue.
