Reproduction

UDrawer with direction="right" and nested props

Description

When using the nested prop of on a Drawer that has a non-default direction (e.g. right), then the nesting effect is not matching the direction. Specifically, the nesting effect remains upwards (which seems the default), even though it that case it should be right-to-left.

Additional context

Claude's analysis indicates this is a vaul-vue bug. The following generated pnpm patch does fix the problem:

     }), !o && ((E = g.value) != null && E.$el) && (G.value = window.setTimeout(() => {
       var k, X;
       const A = ie((k = g.value) == null ? void 0 : k.$el, u.value);

Logs

Start with the UDrawer behavior described for direction="right" and nested, then inspect the generated change location in dist/index.js and the surrounding nested-effect logic. Reproduce the drawer in a Nuxt UI 4.4.0 project and verify that the nesting effect follows the configured direction without regressing the default direction.
