Core | Container: Improve ResizeObserver handling

[rokotyan]

This PR fixes #455, a problem with ResizeObserver throwing an error when scrollbars appear/disappear. Solving this by delaying the resize by one frame.

The only tradeoff is scrollbar flickering when changing the size, but it only appears when "Show scroll bars" setting is set to "Always" on macOS (not sure about the other platforms).

Changelog:

• Use requestAnimationFrame to avoid multiple resize events when scrollbars appear/disappear
• Cancel previous animation frame IDs before scheduling new ones
• Renamed _requestedAnimationFrame to _renderAnimationFrameId

@rokotyan how so I test this? I removed height={400} after a npm run install:clean. Still not resizing for me with vertical changes.
