Link Control overlap Button block toolbar if post edit page includes legacy metaboxes

[shvlv]

Description

I expect the Button toolbar should work regardless Button block place. But the Button block toolbar becomes unusable if the button is placed at the bottom of the page editor with legacy metaboxes.

As far I can see the main problem is 40vh padding bottom available for pages without legacy metaboxes only.

Step-by-step reproduction instructions

1. Install any plugin providing legacy meta boxes.
2. Create a new page and start editing.
3. Fill content equals browser screen height.
4. Insert Button button.
5. Using Link Control add URL.

The expected behavior (without metaboxes):

The buggy behavior (with any metabox enabled):

The issue was fixed, in version 16.8 at least. Perhaps, it's the result of #54286.

The issue came back with the new WordPress release:

It's a duplicate of #63882. And it was fixed last week with #64639. Controls work as expected now:
