The scopes of traverse_mut are empty.

I have defined a HandleVariableDeclaration structure and employed traverse_mut to iterate through the nodes in the program. Within the HandleVariableDeclaration structure, I used Traverse and created the enter_program function, where I defined two new structures. If I wish to continue traversing the nodes using either the traverse_mut_with_ctx method or the traverse_mut method, I need to extract scopes and symbols from ctx. This situation results in ctx.scoping() being empty within the HandleVariableDeclaration structure, and the scopes returned by the external traverse_mut are also empty. How can this issue be resolved?

You need to run oxc_semantic prior to traverse.

TODO:

• update docs
• better panic error message, preferably a debug_assert prior to` run.

Yes, I had run semantic analysis before executing Traverse, and the issue arises because in the enter_program method of the HandleVariableDeclaration structure, I extracted the scopes from ctx and assigned them to a new variable. This resulted in ctx.scopes being empty. The current solution is to convert ReusableTraverseCtx back into TraverseCtx and reassign it to ctx at the end. Is there perhaps a better method?
