Wiki preview does not work on Firefox

[windsource]

When creating a wiki page and using the 'Toggle Preview' button sometimes only 'Loading...' appears.

Gogs version 0.8.0.1212

The bug is reproducable with my own installation and also with https://try.gogs.io/windsource/testrepo/wiki/Home/.

In very rare cases the preview works but most of the time only 'Loading...' appears.

Steps to reproduce:

1. Create a new repository and initialize it with README.md
2. Create a wiki
3. When the very first page is created with the default text press the 'Toggle Preview' button.

The problem seems to be related to using the Firefox browser (v 42.0). I was not able to reproduce the problem using the Chrome browser.
