In various forms (pickings, products etc.) the Note fields do not permit text selection. Why? Is there a fix for this?

(please refer to screenshot - result of CTRL-A in Firefox)

In this example the field is defined in product template:

class product_template(osv.osv):
    _name = "product.template"
    _description = "Product Template"

    _columns = {
        'name': fields.char('Name', size=128, required=True, translate=True, select=True),
        'product_manager': fields.many2one('res.users','Product Manager'),
        'description': fields.text('Description',translate=True),
