[techTania]

Required to load Katex Mathquill4quill dependency on demand dynamically from a component. Facing issues to load the katex mathquill dependencies dynamically (from app.component.ts), sample code.

It is working fine if I give the katex and mathquill4quill links (css/scripts) on the root level (index.html or angular.json) as done here
