Every `refresh()` will trigger 2 layouts for some reason, where the second one does nothing as nothing is dirty, so basically a noop. I can have a look into that (maybe as a follow up?) but I remember that this happens sometimes in general for the `VirtualFlow` and we should check that generally at one point. 

@andy-goryachev-oracle solved that problem in the `RichTextArea` by isolating the method which should be called e.g. two times (due to e.g. `ScrollBar`s) instead of a real relayout.
