Description

The issue was that the select component had the logic to set metadata inside the normalizeSingleValue method and for html5 select component with default value this part was unreachable. As the normalizeSingleValue method is supposed to return the correct value based on type, it shouldn't contain any side effects like set metadata. In that case, I moved that logic to the separate setMetadata method and using it only when the select component is trying to update the value.
