Textbox + Tab View Leads to Errors

Adding a textbox to a tab view leads to AttributeError: 'CTkTextbox' object has no attribute '_x_scrollbar'.

Minimal example:

import customtkinter as ctk


def create_tab_view(parent):
    tv = ctk.CTkTabview(parent, height=0)
    tv.grid(sticky="nsew")
    tv.add("A")
    txt1 = ctk.CTkTextbox(tv.tab("A"))
    txt1.grid(sticky="WE", padx=10, pady=0)


class main(ctk.CTk):
    def __init__(self, parent=None):
        super().__init__(parent)
        btn = ctk.CTkButton(self, text="test")
        btn.grid(row=0, column=0, sticky="nsew")
        btn.configure(command=lambda: create_tab_view(self))


if __name__ == "__main__":
    root = main()
    root.mainloop()

Then just click the button.

In the __init__ of the CTKTextbox class, during the creation of the self._y_scrollbar, it calls self._canvas.update_idletasks() which for some reason ends up looking for the _x_scrollbar as well... which wasn't made yet.

Start in the CTkTextbox init method, focusing on creation of _y_scrollbar and the self._canvas.update_idletasks() call. Reproduce the issue with the minimal example by clicking the button, then verify that adding a textbox to a tab view no longer raises the _x_scrollbar AttributeError.
