It doesn't draw the border correctly when run with `-Dsun.java2d.uiScale=3`:

![Titled Border rendered at 300%](https://user-images.githubusercontent.com/70774172/160433797-df0c54b8-38e3-4902-aef3-db3daf7c7172.png)

All the four images look identically but rendering is not as expected.

On the left and the top, the shadow is 3-pixel wide, the highlight is 2-pixel wide. There's no highlight on the right and bottom side. However, there are 3 light pixels above and below the right-side shadow line, there are also 3 light pixels to the right of the bottom shadow line.

It still has the same bug but at 125% now: the third border has no shadow on the left.
