Broken syntax highlighting for tsx expression with arrow function in attribute  #667

From microsoft/vscode#58810

TS and JS Grammar Extension version: 0.0.45 / latest

Code

const foo = <Foo itemIcon={tabDef.ItemID ? (tabDef.Image || null) : 'Add'} onRenderItemLink={(props) => { }}>text</Foo>; 

The highlighting seems to break after the arrow function attribute

The issue actually starts in the ternary operator, with the left hand side tabDef.Image being scoped as meta.parameters.tsx
