### What kind of issue is this? - [x] React Compiler core (the JS output is incorrect, or your app works incorrectly after optimization) - [ ] babel-plugin-react-compiler (build issue installing or using the Babel plugin) - [ ] eslint-plugin-react-compiler (build issue installing or using the eslint plugin) - [ ] react-compiler-healthcheck (build issue installing or using the healthcheck script) ### Link to repro https://playground.react.dev/#N4Igzg9grgTgxgUxALhHCA7MAXABAWQE8BhCAWwAdMEM8BeXACmFwoEYAaVgJlwF8AlLjoA+XMAA6GXLnRY8MGgBMEMUrRr0mQ0UykyZAHiIB1GAEMKFVSP0GjRAAqwEpStVptcS89nN1gdj5cAHpbaXtcY0JnRTcqDE1eHz8Aim5gsLsjENMLKxs7ASk7RWxYaWiAQQwIbAALVTNLaxgRYEUMFTVMbE1GAT5DXMIausaYZoK2qT4QDjRMADMASwBzFBAV9xg8bEJrcVxHABsoNZWMAHkKbBXMMH5cJZhyXAByACNzT4QTgFoKGcLhh-opzHBsP90JQVidVCElCscO8ANwlDDMOw0ABuK1eGDImmQ4myuBoP3hACUEGAENhiBDGlcMABlaDwBAAMThrnq5gwa1pJKW5hOdLsfFmuDAvmRq1px3MuxWYsMp3OlxudweIgEqPm4HqEAA7gBJDQwDBisAoUXihB8IA ### Repro steps #### Example 1 Let's first see this example **without** a render function: [Playground link](https://playground.react.dev/#N4Igzg9grgTgxgUxALhHCA7MAXABAWQE8BhCAWwAdMEM8BeXACmFwoEYAaVgJlwF8AlLjoA+XMAA6GXLnRY8c7DXpMpMmQB4iAdRgBDChQQwRa9ZqIAFWAlKVqtNrgAme7HrrB2fXAHpT0ua4WoTWMLbkVBjKvK7unhTcPv5mmr46+obGATICUmbh2LDSIQCCGBDYABbGugZGJsCKynwa6YTllTUwdVkmUnwgHGiYAGYAlgDmKCDj9jB42IRG4riWADZQk+MYAPIU2OOYYPy4ozDkuADkAEZ6NwjrALQUm9sYT+F6cNhP6JTjdbGXzOcY4K4AbnyGGYZhoADdxhcMGRlMhxKlcDR7kCAEoIMAIbDEb41XYYADK0HgCAAYoDbFU9BhJgT0aM9OtCWY+ANcGA3GCJgS1noFuNORoNlsdvtDscRAIIUNwFUIAB3ACStGMGE5YBQHK5CD4QA) This produces expected output — we see that when `p1` prop changes, only `PureComponent1` will be re-rendered.
