Description Isaac Shabtay 2007-11-12 07:59:10 UTC

Hello.
Here is a very strange phenomenon experienced with the latest revision (594079).

Consider the attached XSL-FO. As you may notice, there are unexplained blank
lines (after label2/value2, label3/value3, and block1).

The funny thing is, that any one of the following changes will cause the problem
to disappear:

1) Remove the "block-container", so the table is a direct child of the flow.

2) Add "line-height=100%" to the flow.

3) Remove the <fo:block space-before="1.0em"/> which appears right below "Heading".

This is very similar (although not exactly the same) as bug #43815 in which I 
observed that block-containers with position="absolute" caused strange layout 
effects if not all of the 4 properties: left, top, width, and height were 
specified.
