Parsing issue for call expression with type arguments following left-shift

TypeScript Version: 3.8.3

Search Terms: left shift, type parameter

Expected behavior: Syntax highlighting stays intact.

Actual behavior: Syntax highlighting breaks, even with ts-ignore.

Code

function alignof<T>(): number {
  return 1;
}

// works
function foo<T>(): number {
  return 1 >> alignof<T[]>();
}

// breaks
function bar<T>(): number {
  return 1 << alignof<T[]>();
}

// still breaks, does not ignore
function baz<T>(): number {
  // @ts-ignore
  return 1 << alignof<T[]>();
}

Looks like a rescan issue on potentially ambiguous < tokens, attempting to interpret as 1 < <type>.

Playground Link: Provided

Start with the provided TypeScript Playground reproduction and compare the working right-shift example with the failing left-shift example. Inspect parser rescan handling for ambiguous < tokens in call expressions with type arguments. Done means syntax highlighting remains intact for the bar and baz examples, including when // @ts-ignore is present.
