spacy: adding a comma changes the dependency tree

spacy: adding a comma changes the dependency tree
I have noticed that this particular comma changes the dependency tree in a big way:
London broke the world records, and NY will be huge
________________
London broke the world records and NY will be huge
___________
With the comma, the right subtree is "NY will be huge" and without it, it is just "will be huge". It seems to me that "NY will be huge" should be the correct subtree.
I am new with NLP and spacy, so not really sure: Should I report this as a bug or are there other tools to help in these kind of situations?
spacy version '2.0.11'
