- Element name field has no character limit in UI Builder

- Frame Debugger scrollbar gets cut off at the bottom when the Frame Debugger window is maximised
- Frame Debugger docked with the Game View can still be enabled when Game View is maximised and minimised
Resolution Note:
There is no way to a priori know that the amount of work in a compute shader dispatch is too much for the GPU causing a driver timeout. In the future if we get device lost recovery and improved debug info from driver we might have more informative error.
