custom key codes shift+num1[BUG]

[zcaalock]

`configure({
customKeyCodes: {
97: 'num1'
}
})

const keyMap = {
TEST: "shift+num1"
};`

when i press shift then numpad1 it doesn't work, if i do it the other way, numpad1 and then shift it works. Is this bug or am i doing something wrong? f.e, shift+t works as intended no matter what key i press first
