I think that's because `!dx.source` is not generated yet (#204415 yet to be merged), although I thought I removed the check for it before merging this test to main... I mixed things up basically, I'm guessing pre-merge buildbots don't have DirectX enabled to warn me. In any case, I removed all those `ILDB` checks now, they're not really needed here.
