[Resizer] Improve performance by reading offsetHeight from previous frame

[jim-chou-shopify]

WHY are these changes introduced?

Improve performance of Resizer to avoid forced synchronous layout.

WHAT is this pull request doing?

Schedule handleHeightCheck to run in next animation frame

As the JavaScript runs all the old layout values from the previous frame are known and available for you to query.

Verified in playground that it works in dev without timeout and tests passed.

This condition is always true, because this.setMinimumLinesNode is a function and Boolean(Function) is truthy.
