FXML with useSystemMenuBar="true" makes SceneBuilder replace its menu

This is the same issue as JDK-8089659 reported in JDK Bug System.
I report this issue here because it is reproduced in Gluon Scene Builder 8.1.1.

I quote the report content below.

If opened FXML file contains menuBar with useSystemMenuBar="true" then SceneBuilder replaces its own menu with this one. After that entire application is just unusable and must be closed using system menu.

Encountered on revision 8898:33c7a11ad099.

Sample FXML:

<BorderPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8.0.45" xmlns:fx="http://javafx.com/fxml/1">
   <top>
      <MenuBar BorderPane.alignment="CENTER" useSystemMenuBar="true">
        <menus>
          <Menu mnemonicParsing="false" text="File">
            <items>
              <MenuItem mnemonicParsing="false" text="Close" />
            </items>
          </Menu>
          <Menu mnemonicParsing="false" text="Edit">
            <items>
              <MenuItem mnemonicParsing="false" text="Delete" />
            </items>
          </Menu>
          <Menu mnemonicParsing="false" text="Help">
            <items>
              <MenuItem mnemonicParsing="false" text="About" />
            </items>
          </Menu>
        </menus>
      </MenuBar>
   </top>
</BorderPane>
