self.tableView.editing = !self.tableView.editing; bug

self.tableView.editing = !self.tableView.editing;

cell 的高度计算有问题。lable 的宽度是不能自适应。

Start by reproducing the issue around `self.tableView.editing = !self.tableView.editing;` and inspect how cell height is calculated when the label width is not adaptive. No file or test is named, so first locate the table-view cell sizing entry points and determine whether editing changes the layout. Done means the label width adapts correctly and the cell height remains correct in both editing states.
