:nth-child seemingly selects identical siblings

[other-mickk]

I have managed to reduce the situation to the following:

using Gumbo
using Cascadia

tree = parsehtml("""
<a></a>
<a class="xyz"></a>
<a></a>
""")
eachmatch(sel"a:nth-child(1)", tree.root)

This gives me the following result:

2-element Array{HTMLNode,1}:
 HTMLElement{:a}:<a></a>


 HTMLElement{:a}:<a></a>

Adding more children that are identical(ish) to the actual first sibling results in even more elements in the final array. Correct me if I’m wrong, but that shouldn’t be the case. In addition :nth-child(1) is not special, this also happens for other values of the pseudo-selector.

I’m on Julia 1.5.3, which reports the following:

]status Gumbo Cascadia
Status `~/.julia/environments/v1.5/Project.toml`
  [54eefc05] Cascadia v1.0.1
  [708ec375] Gumbo v0.8.0

Thanks for the report, seems like a bug. I'll take a look when I have a moment, hopefully soon, but can't promise.
