The JavaFX CSS parser does not support the combination of short-hand and long-hand notations in a declaration block, as in the following example:

```
.button {
    transition: -fx-background-color 1s;
    transition-easing-function: linear;
}
```

Currently, the long-hand property hides the short-hand property. The expected behavior is that both property notations are combined as if by spelling out all properties in their long-hand form.
