How can I reset the Safari bookmarks in iCloud?

Simplified steps:


 Turn off iCloud Safari sync on all devices
 Backup current bookmarks on Mac
 Delete bookmarks on all devices
 Turn on Safari syncing on Mac
 Restore bookmark backup file to ~/Library/Safari folder
 Turn on bookmark syncing on all iOS devices


The original author of these suggestions noted the following: "Once I turned syncing back on each device remained blank for quite some time. I’m not sure why but I was able to prod the system along by adding a fake bookmark on another device. This seemed to kick everything into gear and I was able to delete that fake bookmark on different device – which eventually deleted it across all devices."
