Unusual behavior of UITextEntryLine when clearing its text

[bennett-nguyen]

I'm having a problem with the UITextEntryLine where every time UI_TEXT_ENTRY_FINISHED fires, it will print out the text and clear the textbox but the placeholder text will stick with the input until I unfocus then focus it again.

I haven't found any relevant information about this problem neither in the docs nor the issues page, am I doing something wrong here?

Code:

import pygame as pg
import pygame_gui as pg_gui

pg.init()

WIDTH: int = 1300
HEIGHT: int = 700
RESOLUTION = (WIDTH, HEIGHT)

HALF_WIDTH: int = WIDTH//2
HALF_HEIGHT: int = HEIGHT//2

WINDOW_WIDTH: int = 700
WINDOW_HEIGHT: int = 500    
WINDOW_RESOLUTION = (WINDOW_WIDTH, WINDOW_HEIGHT)

screen = pg.display.set_mode(RESOLUTION)
clock = pg.time.Clock()
manager = pg_gui.UIManager(RESOLUTION)

layout_rect = pg.Rect((0, 0), (500, 100))

text_entry_line = pg_gui.elements.UITextEntryLine(
    relative_rect=layout_rect,
    manager=manager,
    placeholder_text="this is a placeholder text",
)

while True:
    dt = clock.tick(60) / 1000.0
    screen.fill("white")

    for event in pg.event.get():
        if event.type == pg.QUIT:
            pg.quit()
            exit(0)

        if event.type == pg_gui.UI_TEXT_ENTRY_FINISHED:
            print(event.text)
            text_entry_line.clear()

        manager.process_events(event)

    manager.update(dt)
    manager.draw_ui(screen)

    pg.display.update()
