minor UI: Cancel behavior different when using Cancel Button vs X in dialogs

[BobSilent]

the cancel behavior is different when using the upper right "x" vs. clicking the cancel button

In general the information is not saved, but when clicking the "x" and reopening the dialog the changes are still shown
whereas when clicking cancel button, a real cancel is done and all values get resettet when reopening the dialog.

This is valid for all dialogs, not only for the shown one here:

Expected behavior
Cancel should work same, using x or click the button.
simplest solution, remove "x" in upper right corner.
