Bug: 'self' missing in context

[josephfh]

XState version

XState version 5

Description

self is available to the assign function, which makes it possible to pass the parent machine down to a spawned child machine:

assign({
    spawnie: ({ self, spawn }) => spawn(someMachine, {
        input: { parent: self },
    })
})

However self is not available when specifying the initial context of a machine:

context: ({ self, spawn }) => spawn(someMachine, {
    input: { parent: self },
})

Expected result

It should be possible to deconstuct self in the context assignation

Actual result

It doesn't work. When trying to use context.parent.send(...) from the spawned child:

Uncaught TypeError: Cannot read properties of undefined (reading 'send')
