This is mostly fixed by MDL-36832 which correctly sets the $PAGE->url.
This patch hides the submit and textareas from submission comments in the grading table when
javascript is disabled and quickgrading is enabled. This particular combination results in a form
nested in a form which does not work (and cannot be fixed in a reasonable amount of time).
This was preventing the view full submission/feedback link from appearing
everywhere in the assignment when the submission/feedback content had been
truncated in the summary because it was too long (or too many files)
