Zoom slider events seem to be getting dropped

[msgilligan]

Sometimes (usually) when I move the zoom slider, the image isn't resized until I drag-resize the window. I am on Java 17, mac OS 12.5.1 (on ARM 64) and I am running the example with:
mvn javafx:run -f pdfviewfx-demo/pom.xml -Dmain.class=com.dlsc.pdfviewfx.demo.PDFViewApp

See the attached image, where the slider is almost all the way to the right and the image hasn't been zoomed:

I am experiencing the same problems when zooming the PDF document seems not to work. It only works after dragging the PDF. Any idea where to start to fix the problem?

Follow the slider listener .... or ... if it is bound to a zoom property then follow the listener for that one.
