v1.6.4 Conflict: Multiple assets emit different content to the same filename

[keatkeat87]

Hi all,

After upgrading to v1.6.4, I started seeing this error:
Conflict: Multiple assets emit different content to the same filename

It seems to happen because I’m importing the same font in two places:

1. css
   @font-face { font-display: swap; font-family: Montserrat; font-style: normal; font-weight: 400; src: url('../../src/fonts/montserrat/montserrat-v25-latin-400.woff2') format('woff2'); }
2. html
   <link rel="preload" href="<%= require('../../src/fonts/montserrat/montserrat-v25-latin-400.woff2') %>" as="font" type="font/woff2" crossorigin>

What is the recommended best practice to handle this situation?
Thanks in advance for any guidance!
