Test additional edge cases for components we already have tests for

[rebeccaalpert]

To make sure our APIs stay stable, there's a few tests we could add for each of these components/props:

• AttachmentEdit

• Check if isOpen = false

• filename

• code

• title

• Chatbot

• classname

• innerRef

• CloseButton

• ariaLabel

• ChatbotHeaderMenu

• tooltipProps

• menuAriaLabel

• innerRef

• ChatbotHeaderOptionsDropdown

• tooltipProps

• className

• menuToggleAriaLabel

• ChatbotHeaderSelectorDropdown

• value

• className

• tooltipProps

• menuToggleAriaLabel

• tooltipContent

• MessageBox

• announcement (may be hard to test - don’t worry if impossible)

• aria label

• className

• position - but may be hard to test - ok if impossible

• PreviewAttachment

• code

• isOpen

• title
