fix: size prop can't order corretly.

[GiveMe-A-Name]

Example

.foo { 
   height: auto; 
   height: calc(100vh - var(--header-height, 0rem)); 
}

After lightningcss minify, css code would like this

.foo { 
   height: calc(100vh - var(--header-height, 0rem)); 
   height: auto; 
}

But it's not expect.
we can maintain the last prop, then delete the repeat prop. Like bellow:

.foo { 
   height: calc(100vh - var(--header-height, 0rem)); 
}

fix: #805
