Deleting a shortcut also deletes the row with the same shortcut key

[Zankio]

When deleting the first shortcut, the second one is also deleted.
Eample

1. Shortcut a for site A
2. Shortcut a for site B

Relevant code:

shortkeys/app/options/options.vue

Lines 253 to 256 in 83750b2

	deleteShortcut: function (key) {
	this.$buefy.dialog.confirm({
	message: 'Delete this shortcut?',
	onConfirm: () => this.keys = this.keys.filter(curKey => key.key !== curKey.key)

Should probably be changed to regular reference equality, if that works:

-                onConfirm: () => this.keys = this.keys.filter(curKey => key.key !== curKey.key)
+                onConfirm: () => this.keys = this.keys.filter(curKey => key !== curKey)
