Handsontable 13.0.1 and Flatpickreditor.js date column cut/paste challenge about dataharmonizer

[ddooley]

I tried various experiments in adding a "Paste" option in right click menu. Normally Paste menu item is disabled because Handsontable doesn't think there's anything in its clipboard (self.clipboardCache), but that's because that is not directly connected to system clipboard, which has to be read separately
via navigator.clipboard.readText() or navigator.clipboard.read() -> both of which are asynchronous calls which make getting at what system clipboard contains in the moment quite complicated. I set disabled to false just to test various possibilities of getting at system clipboard. Possibly other browser permissions have to be asked for by code as mentioned in https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Interact_with_the_clipboard

  contextMenu: [
      'copy',
      'cut',
      {
        key: 'paste',
        name: 'Paste',
        disabled: function () {
          /* if (self.clipboardCache.length === 0) {
            var test = navigator.clipboard.readText();
            self.clipboardCache = test;
            console.log("nav1", self.clipboardCache);
            .then((stuff) => self.clipboardCache = ...) navigator.clipboard.readText();
            // try dummy read write text to somewhere? 

          }*/
          return false; //self.clipboardCache.length === 0;
        },
        callback: function () {
          var plugin = this.getPlugin('copyPaste');

          this.listen();
          // BUG: It seems like extra lf is added by sheetclip, causing
          // empty last row to be added and pasted. Exception is pasting
          // of single empty cell
          /*
          if (self.clipboardCache.length === 0) {
            const text = await navigator.clipboard.readText(); //AWAIT isn't allowed here.

            console.log("test", test);
            self.clipboardCache = self.sheetClip.parse(test);
            console.log("nav2", self.clipboardCache);
          };
          */
          if (self.clipboardCache.length > 0)
            self.clipboardCache = self.clipboardCache.slice(0, -1);
          plugin.paste(self.clipboardCache);
        },
      },
      'remove_row',
      'row_above',
      'row_below',
    ],

I have a hack solution for this that seems to be working, via date field right-click menu paste option. Only drawback is no ctrl-v for pasting on that particular type of field. Uploading shortly.
