Fix bug #11007

Browse Source 
The math color inset inherits the mode of the containing inset.
This mode is inferred by the kind of font in effect. Setting the
right mode allows to insert spaces where these should be allowed.
Another small glitch was that the selection was always parsed in
math mode, so that any space was swallowed, even if the inset would
allow them.
