Change order of tasks shown on Roadmap

Is there a good way of rearranging the order that the tasks appear on the roadmap view?

For example:

Currently the Parts procurement duration shows, then Testing duration shows, then the Assembly duration shows (from top to bottom). But is should show Parts procurement, then Assembly, then Test instead.

In the Project for the web, it is in the correct order: Parts procurement, Assembly, Test.

The dates are also in that sequence and no overlaps
