Describe the bug
The mounting sequence for the Progress Hex blocks the main thread for 1-10 seconds due to anime timeline add method. This especially impacts mobile users as the user interface completely freezes for 2+ seconds (on Chrome for Android, running on Google Pixel XL).

To Reproduce

1. Go to home page
2. Search for a package, immediately try to use the UI before loading indicator mounts (i.e. scroll)

For debugging/testing:

1. Set profiler to record.
2. Perform the above steps.

Expected behavior
Progress indicator should not block render or freeze the UI.
