If this issue only occurs in one browser, which browser is a problem?

No response

Describe the Bug

When the Cloudflare adapter is added to the site with its config set to { prerenderEnvironment: 'node' }, the HMR feature of the dev server will not hot-reload any changes made to any files, and the browser must be refreshed manually.

Vite still seems to be sending the reload command, but nothing happens in the browser.

What's the expected result?

When in astro dev mode, the browser content should automatically refresh when a file is saved in the editor.
