Why frame border / line appear after click text widget (the frame is inside canvas) tkinter

i've the problem for make an GUI apps with python tkinter.

here is my sample code

import tkinter as tk

from tkinter import ttk

root = tk.Tk()

root.geometry('300x300')

root.title('CSV Editor')

notebook = ttk.Notebook(root)

notebook.pack(pady=10, expand=True)

tab_home = ttk.Frame(notebook, width=300, height=300)

notebook.add(tab_home, text='Home')

fr_home = tk.Frame(tab_home, background="white")

fr_home.grid(row=0, column=0)

fr_home_container_canvas = tk.Frame(fr_home, background="red")

fr_home_container_canvas.grid(row=0, column=0, sticky='nw')

fr_home_container_canvas.grid_rowconfigure(0, weight=1)

fr_home_container_canvas.grid_columnconfigure(0, weight=1)

fr_home_container_canvas.grid_propagate(False)

canvas_home = tk.Canvas(fr_home_container_canvas)

canvas_home.grid(row=0, column=0, sticky="news")

vsb = tk.Scrollbar(fr_home_container_canvas, orient="vertical", command=canvas_home.yview)

vsb.grid(row=0, column=1, sticky='ns')

canvas_home.configure(yscrollcommand=vsb.set)

fr_home_widget_canvas = tk.Frame(canvas_home, background="yellow")

canvas_home.create_window((0, 0), window=fr_home_widget_canvas, anchor='nw')

fr_home_widget_canvas.config(width=300, height=300, padx=10)

fr_home_container_canvas.config(width=300, height=300)

canvas_home.config(scrollregion=canvas_home.bbox("all"))


text_widget = tk.Text(fr_home_widget_canvas, width = 30, height = 10)

text_widget.grid(column=0, row=0)

root.mainloop()

It is the highlight background which can be removed by setting highlightthickness=0:

canvas_home = tk.Canvas(fr_home_container_canvas, highlightthickness=0)
