Drag to new subfolder command missing

[RealRaven2000]

When dragging email to a QuickFolders tab, we are missing the command "new subfolder...". This menu should be there on dropping mail if the setting is activated in QuickFolders Advanced settings / Mail Commands:

This is expected to append "New Subfolder..." to the bottom of the dropdown menu when an email is dragged onto a Tab. This is now always missing.

Apparently the source code of my function addDragToNewFolderItem() used to clone material from the Thunderbird folder pane context menu - but this is not available to QuickFolders any more:

// New Folder... submenu items
let folderPaneContext = document.getElementById("folderPaneContext");
if (folderPaneContext) {
let newMenuItem = document.getElementById("QF_folderPaneContext-new");
if (newMenuItem) {
    let createFolderMenuItem=newMenuItem.cloneNode(true);
    if (folder.hasSubFolders) {
        let sep = this.createIconicElement("menuseparator","*", popupMenu.ownerDocument);
        popupMenu.appendChild(sep);
    }
    createFolderMenuItem.id=""; // delete existing menu
    createFolderMenuItem.id="QF_folderPaneContext-new"; // for styling!
    createFolderMenuItem.folder=folder;

    createFolderMenuItem.setAttribute("class","menuitem-iconic");

    // use parent folder URI as each starting point
    this.setEventAttribute(createFolderMenuItem, "ondragenter","QuickFolders.popupDragObserver.dragEnter(event);");
    this.setEventAttribute(createFolderMenuItem, "ondrop","QuickFolders.popupDragObserver.drop(event);");  // only case where we use the dedicated observer of the popup!

    // [Bug 26425] option to put 'create new subfolder' on top
    if (prefs.getBoolPref("dragToCreateFolder.menutop"))
        popupMenu.insertBefore(createFolderMenuItem, popupMenu.firstChild);
    else
        popupMenu.appendChild(createFolderMenuItem);
    }
}

So we need to create this menu item from scratch rather than cloning it from Thunderbird...

Fixed version below:

QuickFolders-mx-6.3pre149.zip

this will only copy the label and accelerator key from the folderpane popup, everything else is generated from scratch.

---

To test the new version above, download the zip file, drag the file into Thunderbird Add-ons Manager, do not extract contents or if won't install.
