tbody.childNode.length will report correct length if all elements are contiguous without a newline. viz:
<tbody></tbody>
reports 0 (zero) childNode elements.
<tbody>
</tbody>
or
<tbody />
reports 1 (one) childNode element
If rows are strung as <tbody><tr></tr><tr></tr><tr></tr></tbody>
then tbody.childNodes.length returns a value of 3.
If the source is written as 
<tbody>
<tr></tr>
<tr></tr>
<tr></tr>
</tbody>

then tbody.childNodes.length returns a value of 7 (notice the extra line after the closing tbody tag.

I cannot find a reference to this behaviour elsewhere.

Reproducible: Always

Steps to Reproduce:
1.Create HTML (See additional information)
2.Use JavaScript to detect and report the childNode length 
3.

Actual Results:  
Javascript will always report a childNodes.length of 7, one for each <TR> tag and seemingly one for each newline.



Expected Results:  
childNode.length should be 3.

This error was discovered in Firefox 1.0.7, and continues into Firefox 1.5, on both Windows 2k and Linux.

So as I understand it:
- White space is treated as a child of <tbody> even when <tbody> is expected to have only <tr> as a child.
- Resolved does not mean fixed.
I have difficulty in trying to understand if this is a bug that you believe is fixed in an earlier release, and yet is clearly manifest in 1.5.
Please confirm.
