Description

The bug is specific to usage with the Composition API.
Given options and value passed as a Ref.

When a new option is added to options and also to value to make it selected,
the newly added option is not displayed as selected.

It seems, that the internal state for selected options to be displayed relies on the internal state of available options. But with composable, the internal state of available options is updated before the internal state of selected options.
