e09_row_reordering dropping to the recycle bin doesn't work #139

Closed zoechi closed 8 years ago

zoechi commented 8 years ago

A weird ever-increasing (on-mousemove) drag image is shown and drag-over the recycle bin has no effect.

The exception is fixed (caused by delayed creation of _selectionProxy and _guide to work around a browser issue that causes dnd to break if the DOM is modified inside the dragStart event handler.

The ever-increasing drag proxy image is only in Dartium but not in Chrome.

Dropping onto "Recycle bin" still doesn't delete the rows.
