### Describe the Bug

Zen has 'Essential tabs' which are like pinned tabs that show up on the sidebar.
I have floccus set to sync tabs only.
Whenever floccus is enabled, it periodically rearranges the tabs in my essentials panel. Other tabs seem fine.

### Expected Behavior

Essentials tab order remains unchanged

### To Reproduce

Enable floccus extension and wait a couple of minutes.
