fieldset named selector returns the most outer fieldset instead of the closest ancestor

[cyberwolf]

In an attempt to use the fieldset named selector, it did not return the fieldset I expected it to return when using find() with the legend value as a locator and fieldsets are nested. Instead of the closest ancestor fieldset a legend belongs to, it returns the farthest ancestor fieldset. An example:

• fieldset 1
  • fieldset 1.1
    • legend "a"
  • fieldset 1.2
    • legend "b"

When using the fieldset named selector with the value of either legend "a" or legend "b", in both cases fieldset 1 is returned, while I expected it to return respectively fieldset 1.1 and fieldset 1.2

It would be better demonstrated with a failing test case sent as PR or at least HTML and PHP code posted in here to demonstrate the problem.

@aik099 sure, I'll provide a test.
