Square root power does not work

[Dani-l4]

Hello
I got a problem where square root power not working
It goes like:
[[\sqrt{8 \over 9}]] -> fine looking sqrt
[[\sqrt[3]{8 \over 9}]] -> [[\sqrt[3]{8 \over 9}]]

If I remove the sqrt power its woking fine
I'm using 0.10.0 via https://cdn.jsdelivr.net/npm/katex@0.10.0-rc.1/dist/katex.js
Tried to switch to a fresh version (current is 0.16.9) via https://cdn.jsdelivr.net/npm/katex@0.16.9/katex.min.js
unsuccessfully (actually all formulas stopped working altogether)

Help me please

Maybe try [[{\sqrt[3]{8 \over 9}}]] i.e. wrapping in braces?

It sounds like your issue is with whatever calls KaTeX, not KaTeX itself. What is the [[...]] notation?
