OptionsFunc is not ran on first display of group

[rifelpet]

Describe the bug
I'm using a Select with OptionsFunc where the inputs to the OptionsFunc depend on values from a previous Group.

After finishing the prior group, the Select displays no values until I press a key like the up/down arrows. At this time the OptionsFunc runs and displays the values.

To Reproduce
Steps to reproduce the behavior:

1. Apply this patch to the dynamic-country example:

diff --git a/examples/dynamic/dynamic-country/main.go b/examples/dynamic/dynamic-country/main.go
index 76b56f0..84e2c5b 100644
--- a/examples/dynamic/dynamic-country/main.go
+++ b/examples/dynamic/dynamic-country/main.go
@@ -24,6 +24,8 @@ func main() {
                                Value(&country).
                                Title("Country").
                                Height(5),
+               ),
+               huh.NewGroup(
                        huh.NewSelect[string]().
                                Value(&state).
                                Height(8).

2. Run the example, select a country, and press Enter.
3. Observe the States selection prompt is blank, no title or options are displayed
4. Press any key. The title shows up and after the 1s sleep, the country's states are displayed.

Expected behavior
No key press should be required to display the State select and its options.

Screenshots

Here's a screen recording. Note the delay after submitting the country. I waited a few seconds before pressing a key.
