Description
When you have a indeterminate progress bar a large panel inside a ScrollPane and its scrolled so its out of visible view port. The progress bar should not be running its animation timeline.

NOTE: This probably happens to ProgressIndicator too so should fix that at same time if true.

Does the fix respond to the case of scrollPane, or, for instance, for TableView with ProgressBarCell too?

One simple way to notice it is that the CPU usage will drop within a second or so of the progressbar being scrolled out of the viewport.

How to verify, that it is not animating at the moment?

Is the 100% CPU is a large ProgressBar or on a small device, or are there many off-screen indeterminate ProgressBars?

Made major as this can cause 100% CPU when app is not doing anything.
