Clear multiple cells results in an error

Trying to clear multiple as mentioned in an issue earlier on

    const handleKeydown = (e: KeyboardEvent) => {
        if (spreadsheet) {
            if (spreadsheet.edition) {
                if (e.code === 'Backspace') {
                    spreadsheet.setValue(spreadsheet.getHighlighted(), '', false);
                    e.stopPropagation();
                }
            }
        }
    }

The delete works fine but onBlur I am getting the error below. I am using a fixed column definition set in options

TypeError: undefined is not an object (evaluating 'cell.children[0].value')

Any insight you can give would be greatly appreciated

Start by reproducing the Backspace handler with a fixed column definition and multiple highlighted cells. Trace the onBlur path that reaches the reported cell.children[0].value access; done means clearing multiple cells no longer raises the reported TypeError.
