fix(transformElement): properly transform replaced nodes

[Calvin-LL]

Problem:

I was trying to make a transform that uses replaceNode to replace the currentNode with a new element node.

Since I pass in my transform in TransformOptions["nodeTransforms"], it comes after all the transforms in BaseTransformPreset which includes transformElement.

So

• first, transformElement runs, doesn't do much besides providing an exitFns named postTransformElement
• then my transform runs, replacing the currentNode with a new element node
• once all transforms are finished, the exitFns start running
• postTransformElement runs but uses a reference to the original element node, not the new element node
• my new element node never gets processed by postTransformElement

Even though I can create my own codegenNode in my own exit function, I don't think having postTransformElement transform a node that is no longer in the tree is the desired behavior.

Solution:

Instead of using a reference to the node transformElement is first called with, use context.currentNode
