Should WidgetComponent/Request Render Update take more than a few frames to complete?

Heyo!
I an using a WidgetComponent (for render texture) with Ticking disabled,

and noticed that if I do this:

I need to press the debug key twice for the material to work - it seems like Request Render Update does not finish before triggering the next node (the UpdateReaderScreen updates the material with GetRenderTarget)

If I however put in a delay in between like so:

It works as expected. I have also tried with DelayUntilNextTick and that doesn’t work - unless I use 2 of them in series.

Anyone else experiencing this?
