TikZJax partial global configuration tests

This page tests a partial global configuration applied after TikZJax has loaded.

It verifies that a later partial global configuration is merged with the existing global configuration.

Expected priority:

global configuration
< partial global configuration
< local diagram configuration

Test setup — Apply a partial global fallback image

This page dynamically applies:

window.TikzJaxOptions = {
    brokenImageSrc: "..."
};

Only brokenImageSrc is changed.

The existing global texPackages, tikzLibraries, and other options must remain available.
