Creating GIF with full transparent background from PNGs with semi-transparent pixels, somehow causes this outline

Summary of the bug: There's an unwanted outline, how can I fix it? I created a GIF from PNGs with semi-transparent pixels and it had this outline. When using transparency_color I was able to change the color, but I couldn't get rid of the outline.
This doesn't happen with APNG, but APNG supports semi-transparent pixels. I need it as a GIF though.
How to reproduce:
ffmpeg version = ffmpeg version 4.3.1 built on downloadable .exe from ffmpeg.org
ffmpeg -y -i "sprite2/amongus_player_walk_00%02d.png" -lavfi fps=50,palettegen palette.png ffmpeg -i "sprite2/amongus_player_walk_00%02d.png" -i palette.png -lavfi "fps=50,paletteuse" -y output.gif
One of the original images looks like this:https://i.imgur.com/aCZxKuW.png
the output is this: https://i.imgur.com/9iuJ14K.gif as you can see there's this weird outline, that I'm trying to get rid of.
