What steps will reproduce the problem?
1. Load a large Sheet
2. Frantically try and work on it before it crashes

What is the expected result?
I can continue to work productively

What happens instead of that?
The tab crashes and I have to hard reload the Sheet

Please provide any additional information below. Attach a screenshot if
possible.

1) The Sheet is large and complex but within the size limits of Google Sheets
2) I am using the top-of-the-range Chromebook Pixel LS i7 with 64Gb RAM
3) Chrome OS needs to be able to handle large Sheets more gracefully. As it is, I have to hard reload the tab every few minutes.
4) I can share the Sheet for testing privately if needed.
