Description:
If you use no-break space (Menu/Insert/Formatting Mark) in a text, which you Set as reference (Fields/Cross-reference/Type), the no-break space does not work correctly.

Steps to Reproduce:
1. Write text, turn on Fields shadings (Menu/View)
2. Set some cross-references 
3. Use normal space/no-break space
(see attachment, in my case affected referenced text: "..Pr No..")

Actual Results:
No-break space is:
1. not included in the referenced text, a normal space is used, which cause the division of the text to be put together
2. not shaded in set reference - text (which looks like broken reference text or 2 separate referenced texts)

Expected Results:
No-break space should be:
1. included in the referenced text, with no division of the text to be put together
2. shaded
