Problem
I have a MKV file which has 1 video and 1 subtitle stream, of which I want to hardcode the subtitle stream and output a MP4 file.
Example file, images and results can be found here.

Normally I do the following when hardcoding the subtitles:
ffmpeg -i "original.mkv" -filter_complex "subtitles='original.mkv':si=0" -pix_fmt yuv420p -c:v libx264 -crf 18 "output.mp4"
But this time it gave me an undesired result:
What I would like to see, is the desired result, similar from what I'm seeing in Aegisub:
At this point I'm guessing it possibly has something to do with different colourspaces or pixel formats and/or not using it correctly with ffmpeg. As I'm not really familiar with this, I'm asking for help.
Additional notes
I've hardcoded it both with FFmpeg as well as Handbrake, both giving different results while hardcoding with similar settings. As Handbrake uses FFmpeg under the hood, I did not expect a different result regarding the subtitles, but apparently Handbrake gave the desired result.
Handbrake
All filters off.

Subtitle
The embedded ASS subtitle contains the entry YCbCr Matrix: TV.709, so I reckon that corresponds to the video's BT.709 color space.
I've tried different values for pix_fmt, or adding -filter:s with colorspaces filters, but no luck so far.
As there seems to be no seemingly significant differences in mediainfo, I'm a bit at a loss on what's causing the incorrect colouring. Any bit of help is appreciated.
