Bug description:

Some blocks can be destroyed even if they are above the world border, and some cannot.

Apparently the north and west sides don't allow you to construct/destroy, but the south and east sides allow.

Steps to reproduce:

1. Set the world border to 10.
2. Set the center of the border to an integer value, such as 5 and 8 respectively..
3. Note the blocks in the corners, the south and east corners allow construction, while the north and west corners do not allow.
4. Set the word border center to a float value like 5.1 and 8.1
5. Note the blocks in the corners, the south and east corners still allow construction, while the north and west corners do not, even though they have a larger building space.

Observed results:

Some edges allow construction even if there is a border in the middle of the block

Expected results:

With both set to integer values, the same behavior is expected, allowing or not the construction, since they have the same amount of space between the barrier and the edge of the block.

When there are broken values ​​for the world border center, it is expected that the sides with larger spaces within the border would allow building, but if this is the intended behavior, this is not what actually happens, with the north and west sides being exempt from building at whatever size they are.
