Subject: [PATCH] fix(plugin-react): avoid mangling the sourcemaps of virtual
 modules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously, the `sources` array within a virtual module‘s sourcemap would contain the basename (characters after the last "/") rather than the entire `id` string, which would trigger a "Sourcemap points to missing source files" warning for each virtual module.
