Hi Mike,
You can't directly zoom to the inverted polygon for the display in
composer.
But: you can zoom to the inverted polygon in the main canvas (Right
click on the layer in the legend tree and zoom to layer) and then
synchronize the main canvas and the view in composer.
Use this button (set to map canvas extent):
Or you can interactively pan/zoom to the extent you want with the
following tool:
First select the map element you want to pan/zoom and then use the above
marked tool.
Greetings,
Andreas
