This leads to inputs having the `.ng-invalid` class but still responding to the `:valid` pseudo-state class which breaks the styling based on those classes.\n\n### Please provide a link to a minimal reproduction of the bug\n\nhttps://stackblitz.com/edit/stackblitz-starters-wjqt7b?file=src%2Fmain.ts\n\n### Please provide the exception or error you saw\n\n```true\nNo exceptions or errors.\r\nThis issue can only be noticed visually when styles differ from one state to another.\n```\n\n\n### Please provide the environment you discovered this bug in (run `ng version`)\n\n```true\nAngular CLI: 17.3.8\r\nNode: 18.20.3\r\nPackage Manager: npm 10.2.3\r\nOS: linux x64\r\n\r\nAngular: 17.3.10\r\n... animations, common, compiler, compiler-cli, core, forms\r\n... platform-browser, router\r\n\r\nPackage                         Version\r\n---------------------------------------------------------\r\n@angular-devkit/architect       0.1703.8\r\n@angular-devkit/build-angular   17.3.8\r\n@angular-devkit/core            17.3.8\r\n@angular-devkit/schematics      17.3.8\r\n@angular/cli                    17.3.8\r\n@schematics/angular             17.3.8\r\nrxjs                            7.8.1\r\ntypescript                      5.3.3\r\nzone.js                         0.14.6\n```\n\n\n### Anything else?\n\nNot sure but I remember it working in a previous version.
