No Description When a component is preceded in the same file by another component, the Angular Language service will report the MISSING_CONTROL_FLOW_DIRECTIVE warning twice, and will continue to report it even after it has been fixed. This issue does not occur on the initial load, and it does not occur if the component with the warning is the first or only component in the file.

The gif below demonstrates the language service working normally without the extra component in the file and working abnormally with the extra component in the file. Please provide a link to a minimal reproduction of the bug https://github.com/garrettld/angular-language-service-bug Please provide the exception or error you saw Reproduction steps: - Create a file with two components in it, where the second component is standalone and uses the NgIf directive and imports it directly or via the CommonModule.

Remove the NgIf or CommonModule import from the component, and see the warning that says "The *ngIf directive was used in the template, but neither theNgIf directive nor theCommonModule was imported...." - Restore the NgIf or CommonModule import. Expected result: The warning should disappear. Actual result: The warning remains and is reported twice.
