Upgrade to v11.1.0 causes type method to fill Input incorrectly

• @testing-library/user-event version: 11.1.0
• Testing Framework and version: jest on fresh react-scripts@3.4.1 app
• DOM Environment: jest-environment-jsdom-sixteen@1.0.3

STR:

1. Use CRA to create new app
2. Make the following upgrades:

"@testing-library/jest-dom": "5.9.0",
"@testing-library/react": "^10.2.0",
"@testing-library/user-event": "^11.0.0", ----> "11.1.0" // breaking
"jest-environment-jsdom-sixteen": "^1.0.3",

1. Create a component with textbox input, I just pasted in the input event example from https://testing-library.com/docs/example-input-event
2. Use user.type instead of fireEvent to fill the input
3. Run test with --env=jest-environment-jsdom-sixteen and observe that it fails

What happened:

test('It should keep a $ in front of the input', async () => {
  const { input } = setup()
  await user.type(input, "23")
  expect(input.value).toBe('$23')
})

Expected: "$23"
Received: "$32"

Problem description: type fails to fill the input correctly. If you downgrade to 11.0.0 the test will pass. On another repo this exact upgrade causes an InvalidStateError and I had to reinstall jest-environment-jsdom-sixteen. This comment, https://github.com/testing-library/user-event/issues/307#issuecomment-639222058, also explains another issue I have been unable to reproduce on a fresh app but occurred with the same dependencies.

I figured it out. Pushing a fix in a moment.
