1933139 - inline preview doesn't work on scripts using explicit resource management (with the `using` keyword)

Status: RESOLVED FIXED

(DevTools :: Debugger, defect, P3)

Description

[Nicolas Chevobbe [:nchevobbe]]

0. Turn on javascript.options.experimental.explicit_resource_management and restart Firefox
1. In the console, evaluate the following

{
using x = null
console.log(x)
debugger;
}

2. Hover x in the console.log line

-> no tooltip, and there's an error in the browser console Debugger internal exception: Preview for <onsole.log(x> threw a SyntaxError
