I could reproduce the phenomenon with only 14 instructions on #Intel #GoldenCove, #RaptorCove, #RedwoodCove. It appears only with the 64b-immediate initialization of the 2nd (3rd) operand in the -1024<=imm32<=1023 range.
On #LionCove... 1/2

Of course #Intel #RedwoodCove in #MeteorLake and #GraniteRapids is also involved (it would be a surprise if it wasn't)
