Personally I wouldn't do this, as girls relationships can move around at that age. In my girls classes the were lots of fallings in and out that I heard of.
It certainly doesn't sound like it was kind behaviour from the girl.
However the thing that would decide for me is, are they really friends?
Are they likely to make up?
Does your DD have any wish to be this girls friend going forward?
Your DD is old enough to have an idea regarding this.
If she feels a sort of Yes to the questions, let it go.
If it's a big fat No, then rescind the invite.
But tell your Dd if you do it, it will very likely sour things long term.
If you do do it, text something like "X is still very upset at being abandoned during last weeks playdate and has said the she would prefer if Y does not come to her party now. Whilst the girls might be friends again in the future, I feel it's important to respect X's wishes regarding her birthday party".
Think hard before you doing anything.
Best of luck.
