TR.is(':visible') is not reliable on IE6/7

[Mangos]

If the table is inside a hidden div, which is hidden dynamically, the tr tag in the is(':visible') function will return true on IE6 and IE7.

Please take a look at ​this example

It seems the bug has been fixed two years ago, like ​this tracker #4512. But from the latest version it still fails.

Unfortunately I don't think that this is an edge case that we're going to support. Elements within hidden elements is a very weird edge case that's hard to work against, in general.

Replying to john:

In fact, the element is not always hidden, if the element's visibility is changed dynamically, we cannot get the correct status from the function is(':visible'). I think many frameworks use jQuery as their core Javascript library, you may consider to make this issue as normal, rather than closed it with won't fix.

By the way, we used the workaround for this to check each TD's offsetHeight when if the target is TR and the browser is IE6/7.
