Have submitted feedback, but thought to post a discussion about this also.
Before the Canary update, when we pinned tabs in the browser, they would display the icon for the site. This was ideal for me as it made space for other tabs on the vertical tabs sidebar.
With the latest update, this feature has been changed. It would be nice if we had a setting toggle which allowed us to show site icons for pinned tabs and site icons, and page title for other non-pinned tabs
