Small Yoast and LifterLMS notification conflict

### Reproduction Steps

+ HS-175163
+ Install LifterLMS and Yoast
+ On a course add the LifterLMS login shortcode [lifterlms_login]
+ In an incognito window go to the course and enter dummy information for an account that doesn't exit

### Expected Behavior

+ The LifterLMS notice for "no account found with username/password combination" displays

### Actual Behavior

+ Yoast prevents the notice and it does not display (though this only seems to happen with courses if you add the shortcode on a normal page it's fine)

### Error Messages / Logs

+ Include any relevant error messages or log files
```

```
