ebay-menu-button: labelWithPrefixAndIcon causes key warnings

[mikehobi]

Hello!

When I'm using <EbayMenuButton>, with prefixLabel and text, I get key warnings in the dev console:

browser-init.tsx:11 Warning: Each child in a list should have a unique "key" prop.

Check the render method of `EbayMenuButton`. See https://fb.me/react-warning-keys for more information.
    in span (created by EbayMenuButton)
    in EbayMenuButton (created by InventoryFilter)
    in InventoryFilter (created by InventoryGrid)
    in section (created by InventoryGrid)
    in div (created by InventoryGrid)
    in InventoryGrid (created by MainPage)
    in div (created by ModuleContainer)
    in ModuleContainer (created by MainPage)
    in section (created by MainPage)
    in MainPage

    in button (created by EbayButton)
    in EbayButton (created by EbayButton)

    in div (created by InventoryGrid)
    in InventoryGrid (created by MainPage)
    in div (created by ModuleContainer)
    in ModuleContainer (created by MainPage)
    in section (created by MainPage)
    in MainPage

I've narrowed it down to the labelWithPrefixAndIcon function withing ebay-menu-button/menu-button.tsx

Versions

"react": "^16.12.0"
"@ebay/ui-core-react": "^6.2.1"
