Adjust input by text size

I have a autocomplete that has the option multiple as true . The problem is that when I choose a large text / word, the option to delete it is inhibited as follows a print:

Mycodelookslikethis:

<p:autoCompleteid="event" value="#{manageEventoPermanenciaNavioForm.eventosEquipamento}" label="#{messages['evento.permanencia.eventos.equipamento']}:" completeMethod="#{eventoApontamentoEquipamentoHelper.eventoApontamentoEquipamentoCompleteAtivos}"
                var="bean" itemValue="#{bean.id}" itemLabel="#{bean.identificador}" multiple="true" forceSelection="true"
                queryDelay="500" dropdown="true" />

There is an attribute called inputStyle but I use an old version of primefaces and it does not have this attribute which is 3.4.2. Does anyone know how I can resolve?
