How to refresh bookmark favicons in chrome

I updated favicons for a bunch of my websites. Refreshing the website does indeed show the updated favicon in the browser tab, however the bookmarks for those websites still have the old favicon.

Short of deleting and re-adding each bookmark, is there any way to get Chrome to refresh the bookmarks of each website? Why doesn't just visiting the website update the bookmark icon too?

Have you tried clearing the cache then restarting Chrome? Try that first. If it doesn’t work, then you’ll have to force it as follows.

1. Close Chrome
2. Open your User Data folder
3. Delete the Favicons file
4. Run Chrome
5. Visit sites to force the icons to be re-downloaded

Did you try to force the refresh when you are on the page and press Ctrl + R?

[EDIT] (Credits to James, see his comment) try to refresh and empty the cache with Ctrl + Shift+ R
