Formatting Inserts Extra Space in JSX Element With Function Parameter

[mjbvz]

From microsoft/vscode#15929

TypeScript: 2.0.10 and 2.2.0-dev.20161121

With a jsx file:

(<input ref={() => { return; }} />)

Expected
Running formatting on the document does nothing in this case.

Actual
An extra space is inserted between the two } characters:

(<input ref={() => { return; } } />)

This is inconsistent with how formatting works for other argument types. The issue seems similar to #9823
