Hey,
I tried to reproduce this issue to attach some screenshots but was unable to do so.
Below, I have attached the steps I used to reproduce the issue and a video for reference.

Environment:
WordPress: 6.5.3 | 6.4
PHP: 8.1
Browser: Chrome 125
OS: macOS

Theme: Twenty Twenty-Four

Expected Result due to Bug: According to the bug report, I should have seen the block toolbar or the extra options panel in the block toolbar overflow the page when triggered for the topmost block on the page.

Actual Result: Upon testing, I found that this is not the case. The block toolbar does not overflow the page while the block is within the viewport. The toolbar only goes out of the editor when the block itself is out of view, which is expected behaviour.

Steps Used for Testing:

1. Log In & Navigate: Log in to WordPress and open the post editor.
2. Add Content: Add enough blocks to make the page scrollable.
3. Scroll to Top: Scroll so a block is at the top of the editor window.
4. Select Block: Click the block to display its toolbar and check for overflows.
5. Open Settings: Click the three dots in the toolbar to open the block settings dialogue and check for overflows.
