User is expected to add global CSS for Sigma internals (this is undocumented)

• Sigma.js version : 3.0.2
• Graphology version : 0.26.0
• @react-sigma/core: 5.0.6
• Operating system: MacOS 15.5
• Web browser: Chrome 142.0.7444.60

In a barebones React + Sigma.js app, the app crashes with the following error until the following global style is added:

The error:

Uncaught Error: Sigma: Container has no height. You can set the allowInvalidContainer setting to true to stop seeing this error.

The global style:

.sigma-container {
  background: white;
  position: absolute;
  inset: 0;
}

Upon adding this style, everything works.
This behaviour is undocumented. The FAQ solution for this issue does not work until said style is added. (link)

Live example: TBD (I'm working on it)

We recommend you to create a live example of your issue on CodeSandbox so we can reproduce it. You can start with this template: https://codesandbox.io/p/sandbox/sigma-template-82mpns

Steps to reproduce

• Open official demo app (link)
• Remove style for .sigma-container, which is not a user-class, but an internal class.
• See the following error:

Expected behavior

User should not be expected to set typing for internal library classes. This behaviour is undocumented.

Actual behavior

User has to set styles for sigma internals.
