Name: 3D Viewport Pie Menus (1, 2, 9)
Short description of error
The changing of manipulators seem to be broken on 2.81 with the pie menu. When I try to change between manipulators using Alt - Space, it doesn't do anything.
Exact steps for others to reproduce the error
First I select an object and with the Alt+Space key shortcut I open the pie menu with manipulators. Then I try to select one from the selection which is not currently used, however the manipulator does not switch to the chosen manipulator and stays unaffected.
