"Replace with current URL" is bugged.

Additional info: seems like the bug happens only in incognito mode.(which is my main, that's why i didn't figure out before)

Yes, this can indeed be reproduced in Incognito mode.

However, in my opinion, although it may seem a bit odd, the current behavior is actually expected. This is because the cache data in Incognito mode is isolated from that in normal mode. The bookmark management system attempts to look up the corresponding website icon in the browser's cache. Due to this isolation mechanism, the system can only search within the cache data from normal mode and cannot read the cache data from Incognito mode. Therefore, if you have never visited this URL in normal mode, it will consistently return an invalid icon.
