        <pre>The actual problem here is:
Web Inspector: Minification detection produces false positives for small resources
<a class="bz_bug_link 
          bz_status_ASSIGNED "
   title="ASSIGNED - Web Inspector: Minification detection produces false positives for small resources"
   href="show_bug.cgi?id=161159">https://bugs.webkit.org/show_bug.cgi?id=161159</a>

In the animated GIF you can see that pretty printing is on, even though it shouldn't be enabled by default. When it's on, tabs are replaced by 4 spaces.

When pretty printing is off, tab characters get preserved as expected.
