primefaces: SelectOneMenu: Float Label does not work with selecItem value=null

Describe the bug

Float Label does not work with p:selectOneMenu when there is a converter. Even if there is no value selected, the ui-inputwrapper-filled class is always present.

Reproducer

<div class="field">
<span class="ui-float-label">
	<p:selectOneMenu
		converter="#{produtoConverter}"
	>
		<f:selectItem   />
	</p:selectOneMenu>
	<p:outputLabel
		for="@previous"
		value="AAAAA"
	>
	</p:outputLabel>
</span>
</div>

Expected behavior

The floating label should appear inside the selectOneMenu when there is nothing selected. The ui-inputwrapper-filled class shoud be set only when a value is selected.
