It's a blistering decision, but you gotta pump the breaks, a bit. This type of order for partial summary judgment is exactly the type of thing that is likely to get stayed pending appeal, because if Trump and co. win on appeal (I don't think they will), irreparable harm would already have been done. This will likely take years to sort out.
One thing is clear from reading the decision: this judge (or justice, in this instance) hates tf out of Trump and his lawyers, based on their behavior in this case.
