Favicons for bookmarks broken since Edge v149 update

I've tested this inside a virtual-machine which is running Windows 10 Home 22H2 x32 (OS Build: 19045.6456), which is the 32-bit kernel version and has the final (2025-October-14) public update installed and I was able to replicate the same issue.

Before Microsoft Edge had updated, I created some test bookmarks, and opened-and-closed Edge (ensuring the "Allow Edge to continue running in the background" setting is set to "no", so it is fully-closed in-between tests), and the favicons all remained:

But after it updated to the latest v149 release, some of the favicons broke, and even though you can see Edge has pulled the favicon successfully from the site to display it in the tab, the bookmark does not get updated and remains broken:

I've checked with some family members and friends who are on Windows 11 and none seem to be reporting losing bookmark icons as of now, and they have checked in the Edge settings they are on the v149 release, so maybe this is only broken for Windows 10 users?
