What did you do?
================
1. Set an html page with no CSS styles but browser defaults
2. Set the following CSS styles:
body{display:block;float:none;}
.containerBody{display:block;}
.body_page_holder, .block1{display:block;}
.block1{page-break-after:always;}
.blockTest{display:block;}
3. Define a web page as follows:
<!DOCTYPE html>
<html lang="ja-JP" >
<head>
<style>
body{display:block;float:none;}
.containerBody{display:block;}
.body_page_holder, .block1{display:block;}
.block1{page-break-after:always;}
.blockTest{display:block;}
</style>
</head>
<body>
<div class = "containerBody">
<div class="body_page_holder">
<div class="blockTest">
<div class="block1">
<p> Very long text...</p>
</div>
....... same div class block1 11 times .....
</div> <!-- Closing blockTest -->
<div class="block1">
<p> Very long text...</p>
</div>
<div class="block1">
<p> Very long text...</p>
</div>
</div> <!-- body_page_holder close -->
</div>
</body>
</html>
4. Preview and print page
5. Change blockTest style as follow:
.blockTest{display:flex;flex-flow:column nowrap;}
6. Check that web page was displayed exactly the same
7. Preview and print page
What happened?
==============
- With the first style definition for 'blockTest' class the web page was displayed as expected and printed as expected with each <div class="block1"></div> displayed in a different page as expected by the setting '.block1{page-break-after:always;}'.
- With the second definition for 'blockTest' class the web page as displayed as expected as well but when printing, both preview and print where not as expected:
+ In the first page all blocks where displayed one after another until the end of the page. Blocks not fitting in the page were missing and never displayed.
+ In the second page the first block outside of 'blockTest' block was printed. Subsequent blocks were also printed as expected: each one on a different page.
- The flex block seems to be behaving as follows:
+ All page breaks where avoided, both soft and hard.
+ When printing block behave as if it were set to 'overflow:hidden' cutting the content.
As far as I know this behave is not expected and there is no reason for a flex block to behave differently on screen than when printed (regarding the overflow) hence considering this behave a bug.
What should have happened?
==========================
Both class settings should have produce the same printed material and they did not.
Is there anything else we should know?
======================================

I suspect this report is invalid since flex-flow:column makes the lines
orthogonal to the fragmentainer, but I haven't looked at what the spec(s)
say about this case. Daniel might know.

Yeah, this is supposed to work according to the flexbox spec, but it doesn't work yet in Firefox -- this is a version of bug 939897.
