FFmpeg 4.4 - Incorrect processing of media with timecode

[Andrew]

Summary of the bug: Media with timecode metadata is processed incorrectly. For the sample media, which is ~6.5 seconds with basic timecode metadata output incorrectly has a duration of 10x/fps of 1/10th the original. This results in a file that plays "normally" for the expected duration and then persists the final frame for about 6 minutes.

I have replicated this on multiple original files with timecode information. It does not happen on original files without timecode information. Unclear on the impact of other non A/V metadata/tracks.

How to reproduce: Use of "-map" is required to recreate this issue. Example command:
ffmpeg -i Earth_6s_59-94.mp4 -loglevel error -preset medium -map 0:v:0 -c:v libx264 -profile:v main -x264opts qpmin=0 -bf 0 -pix_fmt yuv420p -g 50 -vsync 0 -tune film -map 0:a:0? -c:a libfdk_aac -b:a 128k -ac 2 -movflags +faststart EarthOut.mp4

Example Source File: Unable to upload this to the form, so here's a link to a file that includes a timecode. Works great in 4.3.1, but 4.4 has bad output - ​https://drive.google.com/file/d/19uPF6_XaCaeKYAcDqSCKcDjuHImC7zQC/view?usp=sharing

Note: 4.4 is not available in the version selection drop-down

I think that vsync 0 is not supported for the mov muxer.
Is the issue reproducible with current FFmpeg git head, the only version supported on this bug tracker?
