Bubble Escape event even if Combobox.Options is not rendered at all (…

…#1104) * bubble Escape event even if `Combobox.Options` is not rendered at all If you use `<Combobox.Options static />` it means that you are in control of rendering and in that case we also bubble the `Escape` because you are in control of it. However, if you do something like this: ```js {filteredList.length > 0 && ( <Combobox.Options static> ... </Combobox.Options> )} ``` Then whenever the `filteredList` is empty, the Combobox.Options are not rendered at all which means that we can't look at the `static` prop. To fix this, we also bubble the `Escape` event if we don't have a `Combobox.Options` at all so that the above example works as expected. * update changelog
