In this commit, we will remove unnecessary uses of the checkValidity
function. In the ListRenderer, during a keydown, we do if checkValidity
but it is an async function so the condition is always true.
We have checked the calls and they are probably unnecessary because
the add(...) function will perform a checkValidity.
