Useless animation when interacting with page list block

[draganescu]

Description

In #48723 a page list which is a child of a navigation block immediately prompts the user to be converted to a list of navigation links if the user tries to select a page list item in the list view or the navigation block inspector.

However, right after clicking there is a half of an exit animation still ocuring below the modal that appears. This is because the animation is configured via a list of blocks that should animate, and that's about it! Sad.

What to do

We need to either upgrade that block animation configuration to an actual API where the animations can be started and canceled programatically, or, even better, move it to a better stage where we implement the Navigator component, and deprecate the "block animation API" altogether because now the Navigator component has been improved as part of the work on the browse mode sidebar.

It'd be good to have a video of the animation in question.
