FormValueParam Test

This appears to be used to unbreak dates that overcomplex datepickers break when we switch to a language that formats the dates differently.

Let's say for example we have a datepicker and it submits the date in the format dd/MM/yyyy - this is interpreted by the base site in the same format and the date is processed. The base site is assuming that the date is in a particular format.

But what happens if we switch to a language that uses MM/DD/YYYY format (US english for example), if the DatePicker is JavaScript or some kind of third party component that is culture aware it will then send the date in the culture format, this means that the base site may well crash when trying to format the date.

For example, let's say the user chooses 31/12/2023 as the date when in UK english. Submitting that date will be processed as 31st of December 2023 and all is well. But let's say they switch to US english (or I believe Korean) and submit the 31st of December 2023 there, this will be sent in the form as 12/31/2023 - when the base site converts it to a UK date it will fall over.

Let's see if we can replicate this issue, probably can't 100% but worth a go

This is the date in the control:
