[Message part 1 (text/plain, inline)]

If I set a box face for a button, and then set a line-space for the buffer, I expect the extra space between lines to be added outside of the box, like so:

+-------------------------+
|          Box            |
|                         |
+-------------------------+
       extra line space
+-------------------------+
|          Box            |
|                         |
+-------------------------+

However, right now, the bottom line of the box includes the extra line spacing, like so:

+-------------------------+
|          Box            |
|                         |
+                         +
|      extra line space   |
+-------------------------+
+-------------------------+
|          Box            |
|                         |
+-------------------------+

Ideally there should be some space between the two buttons on the two lines. Also notice the extra space above the bottom line of the box.

I also attached a repo file to produce these buttons.

If someone can give me some pointers, I can try to look into this.
