Selecting descendants of something:last yields duplicates

[Catrope]

I have a document with two <table> with class="toc", each containing a nested <ul> with a bunch of <li>s. $('.toc * li') will return all <li> elements as expected. $('.toc:last * li') returns all <li> elements in the last table, as expected, but returns each <li> four times. This means, among other things, that $('.toc:last * li').each(someFunction); calls someFunction() four times for every <li>. Example attached.

Test case

I have recreated your test case here  Live Test Case, however using jQuery 1.4.3 this appears to be working fine now.

Replying to addyosmani:

however using jQuery 1.4.3 this appears to be working fine now.

What do you mean by that? Your test case shows the exact behavior Catrope reported. Using Opera 10.62 I get 12 alerts when opening your test saying "One/Two/Three-B" 4 times. Instead of only getting 3 alerts (one for each li).

Another  test case. For every jQuery version > 1.2.6 the result of $('.toc * li').length is different from $('.toc:last * li').length although there is only one .toc element in my test case and thus the results should be the same.

$('.toc * li').length correctly returns the same as $('.toc li').length (3 for my test)

But $('.toc:last * li').length returns the #non-li-descendants of .toc X #of li-descendants of toc (12 instead of 3).,

This seems to happen no matter what PSEUDO selector your use in the selector
