Adding multiple math-fields don't take away focus from old ones / impossible to enter code

[kungfooman]

All those fields are "blinking" and won't stop, no matter what I click.

Example code:

for (let i=0; i<10; i++) {
    const mf = document.createElement("math-field");
    mf.classList.add("mathfield");
    document.body.prepend(mf);
    mf.focus();
}

Just execute in DevTools on your website: https://cortexjs.io/mathlive/

Result:

I can't even write text in the other ones after clicking them.
