Safari. Wrong cursor when dragging

Question

I'm trying to add drag-and-drop functionality to my project and using slip.js for this.

To decorate cursor I've add class="draggable" to each draggable <tr>. The CSS for this class is:

.draggable:active { 
  cursor: -webkit-grabbing;
  cursor:    -moz-grabbing;
  cursor:         grabbing;
}

Drag-and-drop works fine, but in Safari when I'm dragging a table row the cursor looks like cursor: text

In Chrome the cursor is OK

Interesting that when I just click and hold without dragging the cursor is OK in Safari too

Answer 1

As mentioned in chrome sets cursor to text while dragging, why?, I need to disable selection when dragging. My JavaScript for this:

list = document.getElementById('demo1');

var flag_dragging = false;
list.addEventListener('mouseover', function(e){
  document.onselectstart = function(){ return false; }
});

list.addEventListener('mouseout', function(e){
  if(!flag_dragging){
    document.onselectstart = function(){ return true; }
  }
});

list.addEventListener('dragstart', function(e){
  flag_dragging = true;
});

list.addEventListener('dragstop', function(e){
  flag_dragging = false;
});
