contents().hide() results in javascript error, does not hide text nodes

[stevensalter42@…]

If you have a table cell with whitespace or text, and you try to do:

 $cell.contents().hide();

you will get a Javascript error:

Cannot set property 'display' of undefined

The reason is this loop on line 7486 of jquery-1.5.1.js:

  for ( i = 0; i < j; i++ ) {
    this[i].style.display = "none";
  }

Incidentally, I tried simply adding a check to avoid the error:

for ( i = 0; i < j; i++ ) {
    if (this[i] != undefined && this[i].style != undefined)
      this[i].style.display = "none";
}

This prevents the error from occurring, however, it doesn't solve the problem, since the text node is not hidden.

This is not a jQuery "bug", as hide() operates on matched elements (contents returns elements, text nodes and comment nodes), which is documented here: ​http://api.jquery.com/hide

I understand that there are other ways to hide contents that work. I believe the fact that contents().hide() can generate a javascript error is a problem. Even if fixing the effect isn't a priority, I would expect it to hide what it can and ignore the rest without error.
