Description

After a lot of bug searching, I found out that when I use a variable which is None in the with templatetag, it is converted to empty string "". I'm not sure if this is the intended behavior, but if it is, this could be mentioned in the documentation.

in python:
context = { var1: None }

in template:
{% with x=var1 %}
{% if x is None %}
this will not print
{% endif %}
{% if x == "" %}
this will print
{% endif %}
{% endwith %}
