Bug in Opera in TreeGrid columns with align:"right"

[jumple]

In one of your demos I added align:"right" to all the columns and as a result all the record cells are shifted (record cells are wider than headers)
This only happens in Opera

Example is here

Just replace with my version to see

isc.TreeGrid.create({
    width:500, height:224,
    dataSource: employees,
    autoFetchData:true,
    fields:[
        {name:"Name", frozen:true, width:150, align:"right"},
        {name:"Email", width:150, align:"right"},
        {name:"Job", width:150, align:"right"},
        {name:"EmployeeType", width:80, align:"right"},
        {name:"EmployeeStatus", width:80, align:"right"},
        {name:"Salary", width:80, align:"right"},
        {name:"Gender", width:80, align:"right"},
        {name:"MaritalStatus", width:80, align:"right"}
    ]
});
