Describe the bug

Static asset imports, such as background: url('./somebg.jpg') in css, fail to load the first time a page is opened when bundledDev: true is enabled. After a page refresh, they load correctly.

They load correctly on the first page load if I disable bundledDev.

I’m not sure whether it’s related, but there was a similar issue involving React lazy loading and bundledDev: #22454
