Steps to reproduce the problem

2. Dispatch the 'updateviewarea' event to the event bus:
   PDFViewerApplication.eventBus.dispatch('updateviewarea', { source: PDFViewerApplication.pdfViewer, location: { pageNumber: 1, scale: 150, top: 374, left: -174, rotation: 0, pdfOpenParams: '#page=1&zoom=150,-174,374' } });

What is the expected behavior?

The view area changes to the given coordinates.

What went wrong?

The view area stays the same.

Additional context

With everything described, the view area DOES change but only when refreshing the browser. I am doing the dispatching via a button click. Should I do anything else in combination with 'updateviewarea'. I tried reloading the document but that just resets the 'location' data so I achieved nothing, I tried using the 'update()' method from the pdfViewer, again the same thing - nothing.
