Hello out there,
I have found two bigger problems with the drag and drop-ability using two grids. The problem I found appears also on the official example. When you use the horizontal scrollbar, the drag and drop ability disappears on the grid rows. It seems like that there is an invisible mask that listens to the drag and drop, and this mask scrolls away.
The other problem is, that on this mask the mousedown-event drops into a black hole, but on the part where drag and drop does not work, the event is correctly fired. The "black-hole"-effect for (only) onmousedown is even there if you attach the event to the whole document.
I made two screenshots that visualize the problem:
Does anyone know a workaround?
