Starting with the "us" selection in the tray, even if I right click on that icon in the tray and change the input method it goes back to the "us".  Space-Space (the key sequence used to toggle input language in my setup) does not work, and Ctrl-Space which brings up the Japanes IME does not work either.

The issue @andy-goryachev-oracle reported with the Monkey Tester TableView isn't related to this PR or even Linux since I can reproduce it on Mac. As I double-click on cells in the Table View to make them editable Glass is being told to disable the IME most of the time. Sometimes the IME is enabled but I have to figure out a pattern. On Mac disabling the IME turns off the composition window but I can still enter individual Japanese characters which makes the problem less obvious than on Linux.
