Failing to upload tracking annotations to an entire task from UI with multiple jobs

Actions before raising this issue

• I searched the existing issues and did not find anything similar.
• I read/searched the docs

Steps to Reproduce

1. Create a project
2. Create a new task under the project and divide it by segments (10 000 frames here and no overlap)
3. Click Actions > Upload annotation > Select MOT 1.1
4. Upload a gt.zip (with gt and label folder)
5. Upload failing with message: Could not upload annotation for the task

Expected Behavior

Expect 1 annotation file (gt.zip) for the entire task/video to be split into multiple jobs based on frame numbers as stated by the frequently asked question CVAT wiki.

How to upload annotations to an entire task from UI when there are multiple jobs in the task
You can upload annotation for a multi-job task from the Dashboard view or the Task view. Uploading of annotation from the Annotation view only affects the current job.

Possible Solution

No response

Context

Upload tracking annotations to an entire task from UI with multiple jobs is failing. I have tried to create the same task with a single job and uploading the same gt.zip and it is working. It seems CVAT is not able to split an annotation (MOT format only?) file between multiple jobs based on the frame number.

Environment

Ubuntu 22.04 and Docker images
