Bug Description

Clicking on a task to cancel it results in a toast notification to say that it was successfully cancelled. However, the task remains in the task list and you can click "cancel" again (which causes a toast with an error, saying "task not found"). The task only disappears from the list after a short delay.

Steps to Reproduce

1. Start uploading documents to knowledge
2. Open the task sidebar
3. Cancel a task

Expected Behavior

• The cancel button should not be clickable again while the task is cancelled
• Once the task is cancelled it is immediately removed from the task list

Actual Behavior

• You can click the cancel button many times, causing not found errors
• The task remains on the page for a short while

Additional Context

This seems as though the interface is being periodically re-rendered, which is possibly connected to #817.
