Oracle APEX - hidden regions flash on page refresh

On my page there are several region that are hidden or shown based on a condition. I set a variable calculation before regions and then on change of that variable I show/hide various regions. Everything works as expected but I've noticed that when I refresh the page, for a split second I see the hidden regions flash and then disappear. Any way to fix that?

What happens is that the DOM is rendered and once the page is loaded, the dynamic action fires. There is a brief moment between the page fully rendered and the dynamic action firing and that is when you see the component flash. All a dynamic action of type "Hide" does, is set the css style display:none; on the component.

A very simple workaround to prevent the flashing is to set "Custom Attributes" to style=display:none; for the region that should be hidden on page load. That way the component will not show but immediately be hidden.
