Repro Code

ESLint Config

{
  "rules": {
    "@typescript-eslint/no-non-null-assertion": "error"
  }
}a

tsconfig

{
  "compilerOptions": {
    "strictNullChecks": true
  }
}

Expected Result

When using @typescript-eslint/no-non-null-assertion, flagging this code is correct. But the suggested code fix is incorrect. If you apply the fix, you'll get a compiler error from tsc:

2779: The left-hand side of an assignment expression may not be an optional property access. 1:1 - 1:39

Actual Result

Error, but no suggestion.
