Bubbles List takes over terminal

[csg33k]

I've been working on a Proof of Concept and writing short tutorials around bubbletea. I was trying to do what I consider to be a fairly simple change but it seems like I'm doing something wrong.

I have a main model that has references to previewModel and SurveyModel. The PreviewModel takes a struct , generates the yaml representation of it and simply shows a preview of it on updates. The Main Model asks a few questions then once the questions are complete it shows a confirmation prompt (Which I tried to create using the List bubbles ) component.

My root model view, looks correct when I walk through it with a debugger but the preview is never rendered.

func (r *rootModel) View() string {
	windowSize := r.screenWidth / 2
	leftView := activeStyle.Width(windowSize).Render(r.modelsMap[Main].View())
	rightView := noStyle.Width(windowSize).Render(r.modelsMap[Preview].View())

	return lipgloss.JoinHorizontal(lipgloss.Left, leftView, rightView)
}

I pushed the code on here: https://github.com/csg33k/bubbles/tree/main/03_components and you can see a preview of the behavior on here:

(PS. Thank you for VHS I'm having a lot of fun with in capturing behaviors)
