glowsquid 8111d3d63c fix comptime @ptrcasting from a larger type to a smaller one (#31774) ...

closes #30180

Note from mlugg: this fix is very much a hack, but it definitely won't break anything and it demonstrably fixes one case, so I'm merging it for now with the expectation that I'll be replacing the broken code soon.
