Hi,  
When opening context menu from the context menu key in keyboard, if there is no selection, the cursor jumps one line up.

Additional context:

1. Goto [https://phcode.dev/](https://phcode.dev/) , open any text file and click the keyboard right click button to repro the issue.
2. The issue is only present in modern google chrome/edge browser. Its not present in Firefox, Safari, Edge/webkit Web views.

I did a bit of debugging and found the code below:

> var pos = posFromMouse(cm, e), scrollPos = display.scroller.scrollTop;  
> It appears that the code always assumes context menu is opened with mouse. Is this a valid bug or am i doing something/config wrong at my end.

NB: resetSelectionOnContextMenu is set to true as it is expected behaviot

Below is the code fragment extracted from `codemirror.js`

```js
 TextareaInput.prototype.onContextMenu = function (e) {
    var input = this, cm = input.cm, display = cm.display, te = input.textarea;
    if (input.contextMenuPending) { input.contextMenuPending(); }
    var pos = posFromMouse(cm, e), scrollPos = display.scroller.scrollTop;
    if (!pos || presto) { return } // Opera is difficult.

    // Reset the current text selection only if the click is done outside of the selection
    // and 'resetSelectionOnContextMenu' option is true.
    var reset = cm.options.resetSelectionOnContextMenu;
    if (reset && cm.doc.sel.contains(pos) == -1)
      { operation(cm, setSelection)(cm.doc, simpleSelection(pos), sel_dontScroll); }

```

Thanks,
