TYPO3 Core

Its just a little thing which bothers me a bit. Maybe i dont understand this behaviour correctly. I will explain.
If i use displayConds and onChange="reload" on backend fields there is an popup which asks me

"Diese Änderung wird die im Formular verfügbaren Felder beeinflussen. Möchten Sie jetzt speichern, um die Anzeige zu aktualisieren?"

In this Case i can sys "ok" and the form reloads or i can say "cancel" and ther form does not reload, but the choosen value which triggered this popup is changed.

In my oppinion the fields value should be set back to the last choosen to show the correct fields.
Maybe its even better to remove the "cancel" option in the popup because you HAVE TO reload the form to see
the changed fields. Maybe this "popup" can completely removed in this case.
