Under Vaadin 24.9.10 we got an error if we use the slider:
java.lang.NoSuchMethodError: com.vaadin.flow.component.FocusNotifier$FocusEvent: method ‘void (com.vaadin.flow.component.Component, boolean)’ not found
at org.vaadin.addons.componentfactory.PaperSlider.lambda$new$a8baf231$1(PaperSlider.java:41)
It seems that the used FocusEvent constructor is no longer available.
