Background Tasks - Sharing - Percentage Error with Multiple Export: Resets after each completes + lack of "completed" exports

[belisoful]

Apple Feedback Assistant ID: FB15619066

DESCRIBE THE BUG:
I have many very long renders, eg 20 exports of a 12 hour video. Each time an export completes, the Total percentage complete is reset to zero.

As it completes, each line is a time sequence:

|---------------------------------------------|
|*--------------------------------------------|
|**-------------------------------------------|
|***------------------------------------------| <- completes an export
|---------------------------------------------| <- starting work in the next export
|*--------------------------------------------|
|**-------------------------------------------|
|***------------------------------------------|
|****-----------------------------------------|  <- completes an export
|---------------------------------------------| <- starting work in the next export
|*--------------------------------------------|
|**-------------------------------------------|
|***------------------------------------------|
|****-----------------------------------------|
|*****----------------------------------------|  <- completes an export
...
|---------------------------------------------| <- starting work in the next export
|*--------------------------------------------| 
.....|***********************--------------------|
...
... <- Thirdto last video fills 33% of the bar before resetting
... <- Second to last video fills 50% of the bar before resetting
|---------------------------------------------| <- last export
|*--------------------------------------------| 
.....|*******************************************| <- last export completely fills  the bar

I hope this makes sense.

This seems to happen because of the second bug. It could be seen as an enhancement, but it's really a bug due to how it affects the percentage bar.

When an export completes, it is removed from the "sharing" view and so no longer contributes to the "percentage complete." The bug is that the completed exports are automatically removed. But this is also a feature, to retain completed exports. So, a feature enhancement AND a bug! wow.

TO REPRODUCE:

Do multiple exports that will take at least a few minutes to complete while you export other videos as pending.

EXPECTED BEHAVIOUR:

I expect the percentage bar to NOT reset back to zero after each export but continue going up with each completed export. The exports should be retained, and a button should be next to the "Export Complete" to view the file in the Finder with one click. When the completed export "X" is clicked, The percentage complete is only then affected. When all the exports are complete, the "base percentage" goes back to zero and is basically a new "multi-export", whether or not pending exports are added to the percentage.
Removing pending exports would duly affect the total complete percentage in kind.

ADDITIONAL COMMENTS:

This is both a bug and "an enhancement." i prefer the bug side because it's that dimension of "critical" but requires an enhancement to fix.
