Downloads progress is not accurate on the Dynamic Island

Steps to reproduce

1. Download a file
2. Exit Firefox app
3. Note the progress on dynamic island
4. Swipe up and note progress on notification centre
5. Check progress on dynamic island again
6. Wait some time and notice that the progress on dynamic island does not change

Expected behavior

Notification centre progress should be in sync with dynamic island progress

Actual behavior

Notification centre progress is always more in sync with actual download progress than dynamic island or dynamic island does not sync with download progress at all.
