Page List inside Navigation block does not respect justification selection

[Sandstromer]

Description

When creating a menu with the Navigation block and the Page List block, the navigation alignment choice is not passed through to the Page List.

Step-by-step reproduction instructions

Add a Navigation block. Toggle the "Justification" icon, select a justification option e.g. 'Justify items right' In the navigation block, add the Page List block to build a menu.

Expected behaviour

The menu should respect the justification selection.

Actual behaviour

The menu built from the Page List does not respect the justification of the parent Navigation block.

Screenshots or screen recording (optional)

Code snippet (optional)

With the extra UL of the page list, the justification is only applied to the first UL of the navigation block

<nav class="items-justified-right wp-block-navigation">
  <ul class="wp-block-navigation__container">
    <ul class="wp-block-page-list">

 .items-justified-right > ul {
    justify-content: flex-end;
}

Thanks for the report! I took a stab at this one in #29771.

Though, justifications left, center and right work fine for me. I just need to unselect the navigation block to see the change.

Sorry, I should have clarified it is on the frontend that the justifications do not work.

In the editor, it looks okay:

On the frontend, all navigation blocks with page list are displayed the same, regardless of the justification:

Ah, that appears to be a TwentyTwentyOne bug. I am not seeing that in my own theme:

CC: @kjellr @scruffian any thoughts?

[Sandstromer]

@jasmussen I have now tested with other themes and it does appear to be an issue with TT1 so I'll close this.

I'm keeping my PR open as I think the space-between issue is worth looking at. Thanks again for the report!
