`manage_node_deps.py` was changed in https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/2259834 to add line endings at the end of the package.json file However, `npm run install-deps` was not rerun to add the line endings. To prevent future CLs that add deps to include the line ending changes, fix them in this CL.

onetime 
Ensure a function is only called once
When called multiple times it will return the return value from the first call.
Unlike the module once, this one isn't naughty and extending Function.prototype.
Install
$ npm install onetime
Usage
const onetime = require('onetime');
let i = 0;
const foo = onetime(() => ++i);
foo(); //=> 0
foo(); //=> 0
foo(); //=> 0
onetime.callCount(foo); //=> 3
const onetime = require('onetime');
const foo = onetime(() => {}, {throw: true});
foo();
foo();
//=> Error: Function `foo` can only be called once
API

Returns a function that only calls fn once.
