Qt Button changes drastically when setting its `border-radius`.
In a Qt application I have nothing more than a window
with a button as its direct child.

I set its background color and all is fine:

```
Window::Window(QWidget *parent) : QWidget(parent)
{
    button1 = new QPushButton(this);
    button1->setText("1234");
    button1->setStyleSheet("*{background:plum;}");
}
```

![Button](https://software.codidact.com/uploads/flq0vm2x8ky0umjhq10i1dh9kbsm)

But if I also set its border-radius,

```
Window::Window(QWidget *parent) : QWidget(parent)
{
    button1 = new QPushButton(this);
    button1->setText("1234");
    button1->setStyleSheet("*{background:plum;border-radius:0;}");
}
```

the button becomes different in other aspects, namely the background
is not a gradient anymore, the border is gone and it is much smaller.

![Button after zeroing border-radius](https://software.codidact.com/uploads/i9ncw1kc1ax8k99u22bouzh5dwym)

All I expected was for its shape to become rectangular.

What am I missing?

I consulted the [Qt stylesheet reference][1], but that only added
to my confusion, since it states that if not specified `border-radius`
is (already) zero.
