Single Keys binded by bindKeyCombo are not being unbinded by unbindKeyCombo

[jeaniefung]

Describe the bug
it seems like bindKeyCombo prevents conflicts from happening with overlapping bindings(ie. pressing ctrl + L when I have both a ctrl + L shortcut and L shortcut will only trigger the ctrl + L action), however it seems like I can not unbind the combo afterwards. It works if I use bindKey and unbindKey, but I would like to use bindKeyCombo and unbindKeyCombo to prevent side effects with other combinations.

To Reproduce
Steps to reproduce the behavior:

1. Bind a single key with bindKeyCombo
2. Try to unbind the same key with unbindKey or unbindKeyCombo
3. See that the key is still binded

Expected behavior
A clear and concise description of what you expected to happen.
Single keys binded by biindKeyCombo should be unbinded by unbindKeyCombo
