List block affecting Navigation block size

Hello,

I’m running into some bizarre behavior while using the “list block” with the twenty twenty-three theme. The CSS for the list block seems to be adding padding to all <ul> elements on the page. This is stretching the vertical height of our navigation bar on any page using a list block element. For page continuity I’m hoping to be able to control this behavior. Here are some links to two test pages to show examples of this behavior.

https://junejournal2.wpengine.com/2023/09/12/navigation-bar-without-list-block/ -Navigation bar height is properly sized

https://junejournal2.wpengine.com/2023/09/12/navigation-bar-with-a-list-block/ -Navigation bar is now stretched vertically

We would like to be able to use the list block on our pages without having this padding effect added to the navigation bar. Any help resolving this issue is very much appreciated!
