Extreme line spacing when Noto CJK fonts with vertical text

[GoogleCodeExporter]

What steps will reproduce the problem?
1. New document with a CJK text
2. Text orientation changed to vertical right-to-left

What is the expected output? What do you see instead?
The space between the lines should stay the same as in horizontal orientation 
(or similar). Instead it is more than 3 times larger.

What version of the product are you using? On what operating system?
Windows 7 64-bit, MS Word 2007, Apache OpenOffice 4.1.0, LibreOffice 4.2.5.2, 
Noto CJK fonts (Japanese, Chinese S&T, Korean, all weights)

Please provide any additional information below.
Changing line spacing to fixed with some arbitrary value brings the lines 
together. In MS Word however this makes lines of text disappear one after 
another. Attached is a screenshot from MS Word with single line height and some 
of the text highlighted.
