`deno install` installs workspace members' npm dependencies, but not jsr dependencies?

In a monorepo setup, does deno install install the dependencies of workspace members? I couldn't find any mention of this behavior in either the deno install documentation or the workspace documentation, so I'm unsure if this is the expected behavior. Consider the following monorepo structure:

.
├── deno.json
└── packages
    ├── bar
    │   └── deno.json
    └── foo
        └── deno.json

.
├── deno.json
└── packages
    ├── bar
    │   └── deno.json
    └── foo
        └── deno.json

The contents of each file are as follows:

// deno.json
{
  "workspaces": ["packages/foo", "packages/bar"],
  "vendor": true,
  "nodeModulesDir": "auto"
}

// packages/foo/deno.json
{
  "imports": {
    "@std/encoding": "jsr:@std/encoding@^1.0.5"
  }
}

// packages/bar/deno.json
{
  "imports": {
    "chalk": "npm:chalk@^5.3.0"
  }
}

// deno.json
{
  "workspaces": ["packages/foo", "packages/bar"],
  "vendor": true,
  "nodeModulesDir": "auto"
}

// packages/foo/deno.json
{
  "imports": {
    "@std/encoding": "jsr:@std/encoding@^1.0.5"
  }
}

// packages/bar/deno.json
{
  "imports": {
    "chalk": "npm:chalk@^5.3.0"
  }
}

When I run deno install in the root directory, a node_modules folder is created there, and chalk is installed, but no vendor directory is created, and @std/encoding isn't installed. Is this the expected behavior? In other words, is it by design that running deno install in the root directory installs npm dependencies from workspace members but does not install jsr dependencies?
