C-\ (toggle-input-method) indeed toggles between the (inherited) input
method of the parent buffer and no input method, but you can select a
different input method by typing "C-u C-\", which will trhen prompt
for an input method.

You should be able to switch to any input method by using "C-u C-\".
If it works for you, I see no bug here.
