    Fix compilation of ja/Math.lyx (see #9027)
    
    The Japanese math manual was not compiling because of some
    complications with foreign language switching. This would
    have been fixed after the translation from English to Japanese
    is done but I want to make sure the document is compilable
    for 2.1.
