[React@18 QA] @elastic/kibana-visualisations

[markov00]

Part of #203114

How to test

Testing can be done locally by using the PR (#209337) or from main with REACT_18=true ENV flag:

REACT_18=true yarn kbn bootstrap
REACT_18=true yarn start

You can also use cloud or serverless deployment from that PR.

Tip

• Locally you can tell that you're running React@18 by the following message in the console: Kibana is built with and running [email protected], muting legacy root warning.
• When deployed and when having React Dev Tools extension you can check the version with __REACT_DEVTOOLS_GLOBAL_HOOK__.renderers.get(1).version in console

What to look for

Tip

Look for blank screens, error splash screens, unresponsive pages, new errors in the console, unpredictable UI behavior (like laggy text inputs that skip letters when typing fast). You can also review the list of addressed runtime issues discovered by functional tests in the section below

UI Sections we should test

• Charts interactions, rendering
• Agg based Visualize form
• TSVB form
• Vega editor
• Lens editor and inline editor
• Graph
