Form state restore: Need to identify a form by its content

[Kent Tamura]

We'd like to resolve http://code.google.com/p/chromium/issues/detail?id=34351#c10 .

Suppose that the content of page-A is the following at frist:
----------------------------------------------------------------
<form action="PostAction" method="POST">
  <input type="hidden" naem="task" value="AAA">
  <input name="aaa_input1">
  <input name="aaa_input2>
</form>

<form action="PostAction" method="POST">
  <input type="hidden" naem="task" value="BBB">
  <input name="bbb_input1">
  <input name="bbb_input2>
</form>

<form action="PostAction" method="POST">
  <input type="hidden" naem="task" value="CCC">
  <input name="ccc_input1">
  <input name="ccc_input2>
</form>
----------------------------------------------------------------

1. Edit some fields
2. Navigate to another page
3. Browser cache for page-A was cleared, and the page-A is updated to the following:

----------------------------------------------------------------
<form action="PostAction" method="POST">
  <input type="hidden" naem="task" value="AAA">
  <input name="aaa_input1">
  <input name="aaa_input2>
</form>

<form action="PostAction" method="POST">
  <input type="hidden" naem="task" value="CCC">
  <input name="ccc_input1">
  <input name="ccc_input2>
</form>
----------------------------------------------------------------

In the current algorithm, we tries to restore form control states for the ex-2nd form to the current 2nd form.
In order to fix this issue, we need to identify a form by its content.
