@boradakash thx for the huge PR!!!

Looks good to me. I'll merge it in a branch and will take care of a bit of styling for studio, tests, write the doc, release, integrate in our infrastucture, etc.

But before this, I've got first a small question:

• what are the options "Leqno" and "Fleqn"?

Moreover can you please:

• resolve merge conflicts (sorry we did some changes)
• not use var but instead const or let
• replace type definition any with effective definitions
• in the component move extract-math and katex to dependency instead of dev-dependency

But again looks good to me, super 👍

[boradakash]

Okay, will do those changes.

Regarding fleqn and leqno:
fleqn: flush left equations
leqno: left equation numbers

You can find more information from here: Katex
