Rendering a DTL template with a context containing a 'self' key works.
Attempting the same with a Jinja template fails:
{{{
from django.shortcuts import render
def self_test(request):
# Assuming that there exists a DTL style template 'dtl.html',
# and a Jinja template named 'jinja.html':
render(request, 'dtl.html', {'self': 'test'}) # Works
render(request, 'jinja.html', {'self': 'test'}) # Fails
}}}
{{{

}}}
The Wagtail CMS uses 'self' as a key when rendering pages. This error
means that Wagtail can not be used in combination with Jinja templates.
The contents of the templates is irrelevant, and can be blank for testing.
