It shouldn't be much of problem. The solution is to do something similar
to what is done when pressing ctrl+b inside \mathbf inset:
When the user inserts any math element inside \textrm,
lyx should exit the \textrm inset if the cursor is at the end of the inset,
and otherwise the inset should be broken into two.
