Windows: first character input lost on successive programs

[jtackaberry]

Describe the bug

On Windows, if multiple Tea programs are run successively within the same process, the first program runs fine, but subsequent programs lose the first key pressed. The key is silently eaten, after which point the program appears to operate properly until it terminates. Then rinse/repeat for subsequent Tea programs.

This does not occur on Linux or Mac.

Setup

• OS: Windows
• Shell: cmd and Powershell (both affected)
• Terminal Emulator: Windows Terminal, Windows Powershell Console, Command Prompt
• Terminal Multiplexer: none

To Reproduce

1. Build the example in the source code section for windows
2. Run it
3. Type some keys for the first input prompt ("Test 0") and note that it works fine
4. Type a key for the second input prompt ("Test 1") and note that the first key is eaten, and subsequent keys presses are registered

Source Code

package main

import (
	"fmt"

	"github.com/charmbracelet/bubbles/cursor"
	"github.com/charmbracelet/bubbles/textinput"
	tea "github.com/charmbracelet/bubbletea"
)

func Input(prompt, value string) {
	ti := textinput.New()
	ti.Prompt = prompt
	ti.Focus()
	p := tea.NewProgram(inputModel{textInput: ti})
	p.Run()
}

type inputModel struct {
	textInput textinput.Model
	quitting  bool
}

func (m inputModel) Init() tea.Cmd {
	return nil
}

func (m inputModel) Update(msg tea.Msg) (tea.Model, tea.Cmd) {
	var cmd tea.Cmd

	switch msg := msg.(type) {
	case tea.KeyMsg:
		switch msg.Type {
		case tea.KeyEnter:
			m.textInput.Cursor.SetMode(cursor.CursorHide)
			m.quitting = true
			return m, tea.Quit
		}
	}
	m.textInput, cmd = m.textInput.Update(msg)
	return m, cmd
}

func (m inputModel) View() string {
	str := m.textInput.View()
	if m.quitting {
		return str + "\n"
	}
	return str
}

func main() {
	for i := range 2 {
		Input(fmt.Sprintf("Test %d: ", i), "default")
	}
}

Expected behavior

The first key on subsequent Tea programs should not be lost.
