Steps to reproduce the problem:
1. Go to https://tomayac.github.io/chrome-macos-virtual-memory/ in Guest mode.
2. Open Chrome Task Manager and macOS Activity Monitor.
3. Resize the window repeatedly. 
4. Notice how the memory ever increases (see the three consecutive screenshots).
5. Double-click the Chrome Helper task in Activity monitor, notice how it is virtual memory (forth screenshot).

What is the expected behavior?
Virtual memory should not ever-increase upon resizing.

What went wrong?
Virtual memory ever-increases and never goes down.
