Summary: As reported in https://fb.workplace.com/groups/flippersupport/permalink/1033379297142728/, using keyboard shortcuts in one component, can change the state of another. This was caused by two problems: 1. ManagedTable established a global keyboard listener, rather than a local one 2. The Layout Inspector did not stop its keyboard events from propagating up in the DOM This diff fixes both issues Reviewed By: timur-valiev Differential Revision: D26018248 fbshipit-source-id: 23d9cc38ad56d47213cb553ffaf528b05fbe1929
