Datamanager: two ajaxProxy calls with same result

Description

When calling a listview in the admin (e.g. /admin/datamanager/object/?id=gallery) two ajaxProxy requests are fired returning exactly the same result.

The first call looks like:
http://www.abc.de/admin/ajaxProxy/?id=gallery&action=dataManager.getObjectRecordsForAjaxDataTables&useMultiActions=true&gridFields=label,datecreated,datemodified&sEcho=1&iColumns=5&sColumns=...

The second call is exactly the same, except the parameter sEcho=2.

The result of both calls are exactly the same, except the returnfield sEcho (equals 1 and 2).

This effect happens in an old installation with 10.7. and also in a current 10.8.7. One with mySQL, one with MSSQL.
It doesn't result in an error, but the second call seems to be just unneccessary.
