#26110: Admin form escapes postgres JSONField on ValidationError
-------------------------------+------------------------------

To reproduce this bug, let's assume we have this model:
{{{#!python
class TestModel(models.Model):
test_url = models.URLField() # I've chosen URLField as an example but
the specific type of field is irrelevant for this issue
json_field = JSONField(default={})
}}}
The model is added to the admin site the standard way
(`admin.site.register()`) so that we can add content easily. Now, if you
go and submit the following:
`test_url` → `test`
`json_field` → `{"hello": "hola"}`
It'll trigger an expected `ValidationError` since it's not a valid URL.
When the form is rendered and presented back to the user, the `test_url`
will show the incorrect URL while the `json_field` will look like this:
`"{\"hello\": \"hola\"}"`. If the user corrects the `test_url` and submits
the form again, the `json_field` that's being stored in the DB will be the
escaped one.
I can't say if this only happens with admin forms or any form (e.g. model
forms) since I have no time to run proper tests, but I hope this is enough
to track down the issue.
