Fix nested dynamic import CSS preloads

Vite now correctly matches preload markers to nested dynamic imports, preventing CSS from being assigned to the wrong chunk.

Fix CSS preload matching for nested dynamic imports (shulaoda2c53054)

Vite’s build-time import analysis now pairs each import() with the correct __VITE_PRELOAD__ marker using a stack-based match instead of assuming markers appear in simple source order. This fixes nested import().then(() => import()) cases where the wrong chunk could receive the CSS preload, leaving the outer import with void 0.

Other misc changes

  • Added regression tests for marker matching edge cases and nested dynamic imports.
  • Expanded the dynamic-import playground to cover nested preload behavior.
