Examples on pixi website don't seem to be accessible?
I read on the main page that all pixi content is accessible. From a brief look through the accessibility code here on GitHub, it seems content should become accessible (i.e. generate matching HTML) on pressing TAB. However, when I press tab on the examples page https://pixijs.io/examples/#/demos-basic/container.js, nothing happens.
PixiJS has an accessibility module which adds HTML elements for interactive display objects. Because the example you point out has no interactive elements, it would not have any tab-able elements.
Examples that do have interactivity should have accessibility enabled. Would recommend filing an issue or adding a PR to that repo: https://github.com/pixijs/examples.
Main page should be clarified then, that it only applies to interactive elements.
