I'm trying to use lightning:formattedNumber to display a currency value in the same style at the lightning UI.

In a multicurrency org, currency values are rendered as the code, then a space, then the monetary value. e.g.
USD 100
GBP 200
This is consistent when displaying values in page layouts, and in lightning components when using the lightning:outputField component to render a currency field.

When I use lightning:formattedNumber, a space is not included meaning the data I'm displaying does not match the rest of the UI.
e.g.
<lightning:formattedNumber value="100" currencyDisplayAs="code" currencyCode="USD" style="currency" />
renders as
USD100
​Workaround is to render the data myself and work out what locale inconsistencies I don't know about yet.

Can this be logged as a bug?
