Django seems to format all numeric Values including Primary Keys when USE_L10N = True. Intended from Django?

l10n_problem.py

# The Primary Key Field is the "default" from Django ORM - so no explicite definition
# Django==1.8
# USE_L10N = False
<div data-pk="12513" class="empty">
</div>

# USE_L10N = True locale = de_DE
<div data-pk="12.513">
</div>
# USE_L10N = True locale = en_US
<div data-pk="12,513">
</div>
