This is also breaking the xrefs preview updating when changing between certain ILs (LLIL/MLIL and HLIL).

To reproduce:
current_il_instruction.mlil on non-SSA HLIL instructions return SSA instructions.

Other observations:

  1. LLIL_CALL returns .mlil and .hlil as expected (non-ssa)
  2. MLIL_CALL returns SSA for .llil and non-SSA for .hlil
  3. HLIL_CALL returns SSA for both .llil and .mlil

This is a regression in 5.0.7284 on all platforms from 4.2, caught by BNSB-25.
