I have observed what might be a bug. I am using version 8.0.0.
I have added a hook function for the beforeOnCellMouseOver event. The first time I mouse over the cell, the event fires properly and my function runs. However, after mousing out, if I mouse over the same cell again, the event does not fire. If I mouse over a different cell and then come back to the first cell, the event again fires. So, I have to keep moving between cells in order to get the previous cell’s event to fire again.
The mouse out events do not appear to be exhibiting the same behaviour. The mouse out events always fire, even for the last hit cell.
Has anyone else observed this problem?
