Comments pane sometimes shows wrong number of comments in summary heading?

[lexbailey]

Sometimes I see something like "Showing 3 of 4" at the top of the comments pane, when all four comments are clearly visible in the comments pane and on the page. Is this a bug? Or is the "3" actually counting something different???

Argh... Yes, quite, I think there are some issues in that area. It aims to show the number of visible comments after filtering vs before filtering. So without filtering, fully expect these to be equal.
So yes, most likely a bug.......

Aha! that means my testing actually uncovered a bug :)

I was surprised when it failed, seems to be a bit non-deterministic (or at least depends on what mode the browser is in)
