Decomposition of controlled gates not only loses the control information after .decompose(), but also acts on wrong qubits.

In [7]: from qibo import Circuit, gates
   ...: 
   ...: circuit = Circuit(3)
   ...: circuit.add(gates.U3(0, 0.1, 0.2, 0.3).controlled_by(1, 2).decompose())
   ...: circuit.draw()
0: ────────────────
1: ─RZ─SX─RZ─SX─RZ─
2: ────────────────
