I plan to change page automatically after period time from goroutine. But it doesn't work

Expected:

Run go run main.go, after 5 second, Form page will switch to Table page
Actual:
Form page's freezed if we don't touch on it: https://gyazo.com/beb2a6ecfb45e67550bfd5d2d5edd747

It still works if we use button to switch page.

Code:

// Demo code for the Pages primitive.
package main

	"time"

	"github.com/gdamore/tcell"
	"github.com/rivo/tview"

Should your goroutine be calling SwitchPage from within QueueUpdate?
