Fixed #33871 -- Fix bug value cannot be detected after form validation fails

[na86421]

Fixed Ticket #33871

Changes

• After form validation check fails, set form's data as initial data
• Added set_initial_data function in BaseForm
• Added unit test for set_intial_data

Description

It is better to initialize entered data(input) than not to be able to detect and save the changes after invalidation of form. But it seems to hurt ux a little.
