Not working: TextClip positioning and SlideIn effect

[Kinboise]

I'm trying to create a text overlay for my video. Positioning worked well for me in moviepy 1.x, but it always sticks at middle-left after I updated to 2.x. Tried .with_position(('left', 'top')), same result. Plus, SlideIn doesn't work for me while SlideOut does. Thanks!

import moviepy as mp

base = mp.ColorClip((1920, 1080), duration=5)

title = (
    mp.TextClip(
        './SmileySans-Oblique.otf',
        'lorem ipsum dolor sit amet',
        font_size=48,
        color='#fff',
        bg_color='#00000044',
        stroke_color='#000',
        stroke_width=2,
        margin=(40, 16, 8, 8),
        text_align='left',
        horizontal_align='left',
        vertical_align='top',
        duration=5,
    )
    .with_position((32, 32))
    .with_effects([mp.vfx.SlideIn(1, 'left'), mp.vfx.SlideOut(1, 'left')])
)

mp.CompositeVideoClip([base, title]).write_videofile('test.mp4', fps=24)

Expected Behavior

The title text ‘lorem ipsum dolor sit amet’ slides in to (32, 32) from top-left, stays there, and slides out.

Actual Behavior

The text appears at middle-left instead of top-left. It simply appears instead of sliding in. Slide out works, though.
