Hitbox of "close window" button

[Munzu]

First of all, I'm loving the theme, thank you!

My only real problem with it is that the "close window" button is hard to hit compared to, say, the Breeze theme. With Breeze, I can click the most top-right pixel of the window to close it, so it's quite forgiving.

With Sweet, I have to hit the circular close icon exactly, so there is an area in the top-right corner that is not part of the close button. Here's a demo:

Is there any way to expand the hitbox of the close button to the corner of the title bar while keeping the round icon, like how Breeze does it?
