UI-Form; Preloading values for number fields that have a value of zero result in data validation error
Current Behavior
A pre-population message containing a valid payload which contains a value of "0" for a number-type field is filled in on the form, but marked in red presumably to indicate a data validation issue.
Expected Behavior
The expected behavior is that the number 0, when prepopulated for a number field, is determined to be a valid entry.
Steps To Reproduce
A dashboard 2.0 ui-form is added to a flow. The ui-form is given a required field of type Number and some name, such as "Input". The ui-form is set to "reset the form when submitting". The output of the ui-form is sent through a 250ms delay and then back to the ui-form input.
Deploy the flow and enter a value of the number zero for field "Input".
Press submit.
The form with briefly clear and the be re-populated by the delayed messages and contain a value of 0.
The field "Input" will be highlighted with red indicating a data validation error.
If the field is manually cleared and replaced with a new "0", the data validation error goes away.
If the steps are followed again with a value of "1", the data validation error does not present itself.
