#9203: After upgrading ffmpeg from 4.1 to 4.4, concat generates too long video

I have the following command
ffmpeg -y -f concat -safe 0 -i inputs.txt -c copy output.mp4
with
file 'input1.mp4'
file 'input2.mp4'
which in 4.1 generated a 1min video (expected).
I just upgraded to 4.4 and the same command generates a 4min41 video.
Here are the ffprobe for both inputs:
