Here are four small HTML files comprising a frameset:

frameset.html:
<html>
  <head>
    <title>mozilla javascript target frame bug</title>
  </head>
  <frameset cols="50%, 50%">
    <frame src="left-initial-frame.html" name="left">
    <frame src="right-initial-frame.html" name="right">
  </frameset>
</html>

left-initial-frame.html
<html>
  <body>
    <p><a target="right"
          href="link-target.html" 
          onClick="window.location='link-target.html'"
          >click to replace both frames</a></p>
  </body>
</html>

right-initial-frame.html
<html>
  <body>
    <p>(right initial frame)</p>
  </body>
</html>

link-target.html
<html>
  <body>
    <p>if you can see this in both frames, the test passed.</p>
  </body>
</html>

The expected behavior, when you load "frameset.html" and click on the link, is
that both frames load "link-target.html" (the left frame, because of the
javascript, and the right frame, because of the href).

In Mozilla (2001-03-22) the right frame correctly displays the target page, but
the left frame shows up blank. To get the left frame to display correctly, you
must drag the frame divider to trigger a reflow.

Note that this is the simplest testcase I could find. I tried two simpler
testcases: one where there were no frames at all, and the only link was a <span
onClick="window.location='...'">; and one where there were frames but only the
left frame was supposed to update (again, using the span). Both of those cases
worked, so I think this is the simplest one.

It's a slightly pathological testcase, but it shows up more often than you would
think. Some pages commonly are structured in this way, where the left frame
contains a tree view or index of a repository of pages and the right frame
contains the current page of interest. Both pages need to be updated when a link
in the left frame is clicked.

Oracle uses web-based task management software which exhibits this behavior in
Mozilla/Netscape 6. This blocks them from adopting NS6. Nominating for 0.9.

Keyword spammage (sorry about this). Most importantly, nominating nsbeta1 and
marking catfood (indicating oracle employees' dissatisfaction).
