In Qt6, the module's top-level `this` is the module namespace object (e.g. MarkdownIt, MarkdownItTxt2tags), not the QML component scope. So the constructors land on `MarkdownIt.markdownit` etc., and `this.markdownit` in init() is undefined — causing silent init failure and a blank preview. Fix: resolve each constructor with `Namespace.name || this.name` so that Qt6 uses the module namespace and Qt5 falls back to the component scope.

The UMD wrappers in markdown-it, markdown-it-deflist, markdown-it-katex and markdown-it-txt2tags all fell back to `g = this` when window/global/self were undefined, then threw TypeError setting a property on undefined. Fix: insert `globalThis` before the `this` fallback in each UMD chain. globalThis is always the real global object in Qt6's JS engine. In init(), resolve constructors via `_g = globalThis || this` so that Qt6 uses globalThis (where the modules now export) and Qt5 falls back to the component scope (where the modules previously exported via this).
