 Hello everyone!

 I found a strange behavior when I want to change the "Screen Options" in
 the "Appearance -> Menus" area inside the administration interface.

 Lets assume that in the first step all checkboxes are selected:

 Now I deselect all "Boxes" checkboxes:

 After that I leave the "Appearance -> Menus" page (lets go to the
 dashboard for example) and go back to it again.

 When I try to unselect one of the "Show advanced menu properties"
 checkboxes like the "Title Attribute", leave the "Appearance -> Menus"
 page and go back to it, the checkbox is selected again. Sometimes even all
 of the "Boxes" checkboxes are selected again.

 It is not always possible to reproduce it because the problem does not
 occur everytime and seems to be a little bit random. Sometimes if I
 unselect all "Boxes" checkboxes and come back to the page, some of them
 are selected again. Another example: If I select two/three of the "Boxes"
 checkboxes after all of those checkboxes were unselected and refresh the
 page, all or some of the not-selected "Boxes" are selected as well.

 I tested this with version 4.4/trunk on different sites with different
 browsers (Chrome/Edge) and different themes (default and own).

 I hope someone can reproduce this problem too. If not I can try to upload
 some screen capture later.
