Keybindings not respected when unsetting multiple shortcuts

[HavinLeung]

Description

keybindings.json not respected if trying to unset multiple shortcuts.

• Can you reproduce the issue?

Steps to reproduce

1. Create keybindings.json
2. Overwrite two id's with "" as accelerator. I used "edit.find-in-folder" and "format.inline-code"
3. Restart Mark Text

Expected behavior:

The shortcuts should now have no keybinding.

Actual behavior:

both shortcuts have the original keybinding

example:

{
	"edit.find-in-folder": "",
	"format.inline-code": ""
}

current workaround:

{
	"edit.find-in-folder": "",
	"format.inline-code": "F1"
}
