It didn't render as except, and render class in a strange way

[TheRaindrop]

When I code like that, the boxed part didn't render any class, like show in the below

But when I add a new line like this

It's OK now!!! But it is unpridictable, I can't code in this way

So, what's the problem

@TheRaindrop Check if disabling babel cache solves your issue.
