border color is not working when shape type is rectangle.

[ghost]

Hi.

When I using rectangle shape type, border color is not working.

I found that if shape is circle or square, border is working but triangle and rectangle is not working.

Can you check it?

Also, is it possible using "\n" on top title or bottom title?

For example, I want to show "AB" on top title like "A (next line) B".

I tried "A\nB", "A\rB", "A\n" and others but not working.

Is this possible?

Thank you for your work.
