The questions to ask yourself: 

Have you chosen to display the wording?

If you have chosen to hide the wording, have you provided a placeholder (replacement text)? 

Have you put this placeholder in all translations of this form? The form is available in the browser’s language. Consider all of your visitors :)

Is the display problem linked to your website?

Look at the preview in Plezi, test the form’s script at jsfiddle
