Cocos Creator Label Size Not Updated: updateRenderData and Next Frame

Refresh Label Render Data before Reading Size

Immediately after changing Label text, its UITransform may still contain the previous dimensions. Waiting until the next frame works, but explicitly updating render data is clearer:

const label = node.getComponent(Label);
label.string = 'Updated text';
label.updateRenderData(true);
const size = node.getComponent(UITransform).contentSize;
