Filter in a table (user or group or test results...) go back to default if we do any action
when viewing datas from table, a teacher can choose the number of item to view, or to filter with a group ...
when doing any action, teacher complains they have to redo the filter of their table.
e.g. they chosse to veiw 50 items of the table, they click on a action, and when they go back to the table, they still see 20 items (defaults)
e.g. when thet filter the test results table by Group, and click on Correct the test, they have to redo the filter (and wait for the filter table to be displayed) when they go back to the table.
