Slot with props doesn't propergate changes

[RedHatter]

Describe the bug
If a slot that passes a value back contains another slot then any changes to the value will not propagate through.

To Reproduce
Here's a repl. Outer.svelte renders a slot and passes text='first' then updates it to 'second'. Inner.svelte simply renders a slot. It should render first first then after a second change to second second but it instead changes to second first showing that the inner slot is never notified of the change.

Severity
At work I'm re-writting a very large application in svelte. I'm running into this bug frequently do to how we handle state. This very much needs to be fixed before we can push to production.
