Hello - firstly, really love tview and this framework - it's fantastic! Thanks a ton for creating it and continually working on it! It's driving TetraTerm, my remote scene visualization tool for games made with my 3D renderer Tetra3D. Really loving how flexibly it displays while working from a terminal.

The issue I'm having is that when an Application has mouse support enabled via Application.EnableMouse(true), TreeViews can no longer scroll using the mouse wheel. Here's a reproduction program adapted from the example in the wiki for TreeViews:


package main

import (
	"github.com/rivo/tview"
)

func main() {

	root := tview.NewTreeNode("Root")

        // Create enough nodes to need to scroll
	for i := 0; i < 20; i++ {
		root.AddChild(tview.NewTreeNode("Node"))
	}

	tree := tview.NewTreeView().SetRoot(root).SetCurrentNode(root)

	app := tview.NewApplication().SetRoot(tree, true)

	// Uncomment the line below and scrolling with the wheel stops working
	// app.EnableMouse(true)

	if err := app.Run(); err != nil {
		panic(err)
	}

}

This example works fine, but if you uncomment the app.EnableMouse(true) line above, the mouse wheel no longer scrolls the tree view.
