Issue:
Content of all tabs of a UITabContainer become visible when showing the UIWindow that contains UITabContainer
**Describe the bug**
When you call "show" on a UIWindow containing a UITabContainer, the contents of all tabs become visible.

**To Reproduce**
Steps to reproduce the behaviour:
1. Run the reproducible example below
2. Close the UIWindow object
3. Click the UIButton object to show the window again

**Expected behaviour**
I expected that only the content of the last selected tab to become visible.

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Platform and software (please complete the following information):**
 - OS: Ubuntu 24.04 LTS, Linux Kernel 6.8.0-40-generic x86_64
 - Pygame GUI version: pygame_gui        0.6.12
 - Pygame version: pygame-ce         2.5.0


Reproducible example:
```python
import pygame as pg
import pygame_gui as pgg

SHAPE = (800, 600)
pg.init()
pg.display.set_caption('Quick Start')
clock = pg.time.Clock()
manager = pgg.UIManager(SHAPE)
window_surface = pg.display.set_mode(SHAPE)
background = pg.Surface(SHAPE)
background.fill(pg.Color('#000000'))

class MyWindow(pgg.elements.UIWindow):
    def on_close_window_button_pressed(self):
        self.hide()

btn = pgg.elements.UIButton(pg.Rect(32, 32, 120, 24), 'Show window')
win = MyWindow(pg.Rect(32, 64, 320, 480), manager, 'Janela')
tabs = pgg.elements.UITabContainer(pg.Rect(0, 0, 320, 480), manager, win)
for i in range(4):
    tab = tabs.add_tab(f"Tab{i}", f"tab{i}")
    lab = pgg.elements.UILabel(
        pg.Rect(16, 16+24*i, 120, 32), f"Label for Tab {i}",
        manager, tabs.get_tab_container(tab))

is_running = True
while is_running:
    time_delta = clock.tick(60)/1000.0
    for event in pg.event.get():
        if event.type == pg.QUIT:
            is_running = False
            break
        if event.type == pgg.UI_BUTTON_PRESSED:
            win.show()
        manager.process_events(event)
    manager.update(time_delta)
    window_surface.blit(background, (0, 0))
    manager.draw_ui(window_surface)
    pg.display.flip()
pg.quit()
```
