Description:
Equations containing formatted text, such as bold or non-italics loose the format when loaded in LO Writer. So, all text in equations becomes italics and non-bold, as is the default for math variables. MS Word allows that formatting but LO Writer ignores it.

Such formatting is important sometimes: e.g. for vectors and matrices (often bold and non-italics) or units (usually non-italics.



Steps to Reproduce:
1. Create a .docx file containing formatted equations
2. Open it in LO Writer


Actual Results:
Formatting lost

Expected Results:
Formatting retained.


Reproducible: Always

BTW. I thought maybe LO does not support such formatting, but it does.

bold{...} -> sets bold
"..." -> sets regular text, i.e. non-italics 

So an equation with this code would do it:

bold{"B"} =k bold{"A"} ^ {-1}
