Site Logo Block: when set as Site Icon, W menu doesn't update

[annezazu]

Description

After updating to 13.8, when adding a site logo block, adding a logo, and setting it to "use as site icon" the W menu doesn't reflect the change. Instead, it continues to just show the WordPress logo. cc @priethor @Mamaduka

Step-by-step reproduction instructions

1. Go to Appearance > Editor.
2. Add a Site Logo block.
3. Add a logo.
4. In the block settings for the Site Logo block, toggle on the "Use as site icon" option.
5. Notice that the site icon updates but the W menu/navigation component doesn't update.

I can reproduce the same issue on 13.7, so probably not a new regression.

We discussed this in #38555 and #38575 and discovered that this same issue occurred when the Gutenberg plugin was inactive. Can someone confirm whether the work here has any impact on that?

[Mamaduka]

@carlomanf, the issue exists in WP 6.0 as well. This change needs to be backported into the core for a fix.

We were finding the issue in version 5.9 actually. Just want to verify if that is also your understanding?

[annezazu]

@gziolo want to flag this as consideration for 6.0.2. @carlomanf curious to hear more about what you were/are seeing with 5.9?

[carlomanf]

@annezazu According to #38575 (comment) the site icon failed to show up in core version 5.9 if the gutenberg plugin was inactive, and only showed up if the gutenberg plugin was active. Not sure of the behaviour pre-5.9.

Ah thank you! This should make it into 6.0.2 so hopefully we can get this fixed once and for all :)
