If you have a multiple page form and you go back a page within the form (maybe to changed something on page 1) the titles come back and page holders are gone until you refresh the page (but then you lose everything you wrote/selected).
This also happens when there is an error. Lets say someone missed a field and pushes next or send. The form shows the red error message but again, the titles come back and placeholders are gone.
Still love the plugin, maybe a fix soon?
