Expected / Desired Behavior / Question

Proper evaluation of validation formula =len(internalColumnName)>6

Observed Behavior

Considers strings with length >6 to be not valid.

Steps to Reproduce

Add column with validation formula =len(internalColumnName)>6, check how it does not consider strings that are longer than 6 as valid even though the default SharePoint form does

Here length is used as length function, but it should be len as far as I understand (https://support.microsoft.com/en-us/office/len-function-038f2e0d-57d3-4f35-ae74-9a79d66e8fc2)
