ref.cast fails on global initialized with same struct type

[akldc]

Describe the bug
There appears to be a bug in iwasm when handling ref.cast on a global initialized with a struct of the same type.
The following WebAssembly module reproduces the issue:

(module
  (type $0 (func (result (ref struct))))
  (type $1 (struct (field (mut i32))))
  (global $0 (mut (ref struct)) (struct.new_default 1))
  (export "main" (func 0))
  (func $0
    (type 0)
    (global.get 0)
    (ref.cast (ref 1))
  )
)

Running this module on iwasm results in the error:

Exception: cast failure

Running the same module on Wasmtime or Wasmedge executes correctly and returns a reference of the expected struct type.
The global $0 is declared as (mut (ref struct)) and initialized with struct.new_default 1, i.e., an instance of type 1.
According to the specification, casting a reference to the same type should succeed, not trap.
If global.get 0 is replaced with struct.new_default 1, the expected result is obtained. Therefore, this bug is related to the global.

Version
iwasm 2.4.4
ubuntu 20.04

To Reproduce
Steps to reproduce the behavior:

1. Compile iwasm with flags like '-DWAMR_BUILD_JIT=1 -DWAMR_BUILD_TAIL_CALL=1 -DWAMR_BUILD_GC=1'
2. Run iwasm with CLI options like 'iwasm -f main test1.wasm'
3. See error

Expected behavior
ref.struct

Actual Result
Exception: cast failure
