[BUG] Configuration.option('_customKeyNamesDict') not set when trying to retreive a custom key with ObserveKeys only property

[kgagnon]

Describe the bug I have a <GlobalHotkeys> component and some hotkeys defined (as strings) and passed to the keyMap property. I then have an Input wrapped with <ObserveKeys> component that has the only property set to ["ctrl+enter"] (which is my hotkey string set in the keyMap)

Expected behavior The editable field wrapped by ObserveKeys should block all hotkeys previously set but one, in our case, ctrl+enter

What happens instead js TypeError when trying to get "_customKeyNamesDict" from the configs @isCustomKeyName.js:9

Platform (please complete the following information):

• v2.0.0
• firefox72.0.1 (64-bit)

Include the smallest log that includes your issue: Here is console output:

Setting verbose output won't do anything since it is a fatal error. If anything, I can see my key bound to the handler and that it is correctly set (right before the crash):

            {
                "prefix": "",
                "actionName": "submitConditionForm",

                "id": "Control+Enter",
