v2.3.0-alpha.0 Performance Rendering React

[Lily418]

Between v2.2.3 and v2.3.0-alpha.0 speed of rendering has decreased

To Reproduce
Steps to reproduce the behavior:

1. Running the Material Package Examples
2. Choose "Huge Test" example
3. Observe that in v2.3.0-alpha.0 when typing in a field takes ~0.5s to render, v2.2.3 is noticable faster to render

Browser (please complete the following information):

• Browser Firefox
• Version 67.0.2

Used Setup (please complete the following information):

• Framework:React
• RendererSet: Material

Additional context
I'm going to run the React Profiler to see if I can determine the cause

Ah looks like #1406 is about this

[edgarmueller]

Yes, indeed, we noticed that performance degrade as well and working on it. Thanks for report.

[edgarmueller]

This should be fixed via #1406. If you experience significant slow-downs related to the context-based API, please re-open.

Is this still an issue @edgarmueller? Editing a text item in a nested array causes tons of re-renders as shown below.
