In the Text command, try adding an additional line above and and below the equation and that should provide a buffer around the equation.
You do this by clicking the plus symbol to the right of a line (see the attached image). Note that these lines can be clicked and dragged around, so you can add two lines and then drag the line with the equation to the middle.
It is a bit of a work around, but does that provide the background you need?
