TX3G Subtitles with italics tags are sometimes small when srt is embedded in mp4
I made an MP4 with Subler (https://subler.org/donate.php), with video, audio and subtitles tracks that were fallen from a truck (https://www.youtube.com/watch?v=kccONko4xYE).
The subtitles are standard .srt with some italics tags (attached the sub file, shouldn't break copyright).
What happens is that some captions are smaller than others. Sometimes the whole caption, sometimes just some words. Something is profoundly broken here. I'm attaching screenshots.
If I leave the .srt file next to the video file (originally an mkv, but I also tested with the final mp4 by using Subtitles menu > "Add Subtitles File…") the subtitles render correctly, all at the same size.
If need the source let me know.
