[posila][0.17.62] Power pole coverage not shown when non-existent gui is present

[Jon8RFC]

In some instances, the power pole's coverage areas aren't shown when holding another pole if there's some kind of false "GUI in the way" situation. This can be readily showcased with the shortcut menu open, which creates a larger area than exists. There are other instances below the minimap where it's not shown if entities are there, but if entities aren't there it shows just fine.

Thanks for the report.
