Curious behaviour of number field in form

[lozdown]

I have a form with a number field. This field needs to accept either an integer or real value input. However it will not allow me to enter a real number.

This is a cut down version of the form

select 'form' as component;
select 'amount' as name, 'number' as type;

If I input a value e.g. 20 the form accepts the value. If I input 20.7 it will reject the value and show a message 'Please select a valid value. The two nearest valid values are 20 and 21.

Why is this and how do I configure the form field to accept integer and real values?

You can use the step parameter to configure the granularity of the input.

select 'form' as component;
select 'amount' as name, 'number' as type, 0.01 as step;
