Starting stopwatch multiple times increases speed

[ipsavitsky]

Describe the bug
When applying multiple stopwatch.Start commands, stopwatch starts ticking faster with each one.

Setup
Please complete the following information along with version numbers, if applicable.

• OS Ubuntu
• Shell bash
• Terminal Emulator kitty
• Terminal Multiplexer zellij
• Locale en_US.UTF-8

To Reproduce
Steps to reproduce the behavior:

1. Compile code
2. Run program
3. Press enter a couple times, sending a Start command with each one

Source Code

package main

import (
	"log"

	"github.com/charmbracelet/bubbles/stopwatch"
	tea "github.com/charmbracelet/bubbletea"
)

func main() {
	p := tea.NewProgram(initialModel())

	if _, err := p.Run(); err != nil {
		log.Fatal(err)
	}
}

type model struct {
	stopwatch stopwatch.Model
}

func initialModel() model {
	return model{
		stopwatch: stopwatch.New(),
	}
}

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

func (m model) Update(msg tea.Msg) (tea.Model, tea.Cmd) {
	var cmds []tea.Cmd
	var cmd tea.Cmd

	switch msg := msg.(type) {
	case tea.KeyMsg:
		switch msg.Type {
		case tea.KeyEnter:
			cmds = append(cmds, m.stopwatch.Start())
		case tea.KeyCtrlC:
			return m, tea.Quit
		}
	}

	m.stopwatch, cmd = m.stopwatch.Update(msg)
	cmds = append(cmds, cmd)
	return m, tea.Batch(cmds...)
}

func (m model) View() string {
	return m.stopwatch.View()
}

Expected behavior
Stopwatch starts with the first press of enter and keeps running at expected speed with every subsequent Start message
