Word 2010 - The font "Cambria Math" causes display problems

The font "Cambria Math" (not the regular "Cambria") causes display problems within Word 2010: whichever font point size is chosen, the characters seem to appear enormous (so large that only a small portion of them can be displayed).
See attached screenshots:

• ROS_Word2010_CambriaMath_bug1.png: the single character in "Cambria Math" font looks certainly large, due to the huge selection zone appearing on Word (background); the text sample in the font selection dialog also appear huge, and this is the only font that possess this behaviour. All the other fonts display correctly.
• ROS_Word2010_CambriaMath_bug2.png: however, this problem does not seem to appear everywhere: the font is correctly visualised from within the ReactOS font viewer. Also, text in "Cambria Math" is correctly displayed within e.g. ReactOS WordPad.

It is also worth noting that Cambria (Math) is found within a TrueType Font Collection (TTC) file.
