Whitespaces in HTML source code seems to be effecting table rendering.  I do
hope it's nothing stupid I'm doing but...  The following page is rendered
incorrectly

The following page is rendered correctly

Notice the menu below the orange stripe's spacing.  It moves between the 2 files
and the only difference is the addition of white space in the source between
picture elements (see source) 

I'm having this same problem on Windows 2000 Moz 1.3, 1.4a and RedHat Linux 8
Moz 1.3, 1.4a

Reproducible: Always

So...

<img> <img>

should have a space between the images.

<img><img>

Should not.  That's what's happening here. What's the bug exactly?

Attachment: shows problem

I'm sorry.  it's not the best example, but it does illustrate the problem. 
I've attached a gif which hopefully points out the problem better.  I didn't
have a lot of free time to make a simplified test case, so I just posted what I
was working on.  If I have some time over the next few days I'll try to post a
better example.

dup of bug 22274 ?

Comment 5

[Boris Zbarsky [:bzbarsky]]

Ah, yes, except in reverse.  The page is using a 4.01 Transitional doctype,
which means that it's in almost-standards mode.  The only difference between
standards and almost-standards is that we have the quirky box model in
almost-standards so people don't hit bug 22274.  What that means, of course, is
that adding whitespace to the cell _will_ affect its height if the font size is
larger than the image heights...

Nick, does changing to a 4.01 Strict doctype make the two pages render identically?

[Nick Pietraniec]

Yes. (vertical alignment is same)

Then this is all working like it's supposed to be, looks like.
