When uploaded file size is greater than `FILE_UPLOAD_MAX_MEMORY_SIZE`,
Django uses `TemporaryUploadedFile` to represent the file object. However,
when executing `.copy()` on a `QueryDict` containing such a file, the
returned object has the file but it is in closed state (`seekable()` is
`False`).
**Expected**: File should present in open state (`seekable()` should be
`True`)
Below is a reproducible example and also contains version details:
{{{
Python 2.7.12 (default, Dec 4 2017, 14:50:18)
In [18]: import django
In [19]: django.VERSION
Out[19]: (1, 11, 11, u'final', 0)
In [20]: from django.http.request import QueryDict
In [21]: from django.core.files.uploadedfile import TemporaryUploadedFile
In [22]: d = QueryDict(mutable=True)
In [23]: f = TemporaryUploadedFile('test.jpg', 'image/jpeg', 100, 'utf-8')
In [24]: f.seekable()
Out[24]: True
In [25]: d.appendlist('image', f)
In [26]: d['image'].seekable()
Out[25]: True
In [27]: c = d.copy()
In [28]: c['image'].seekable()
Out[28]: False
In [30]:
