Mandatory field not show the exclamation mark

[liyongscb]

In ADO, we have some field customized with the multivalue control extension, we set the field to mandatory in layout page. THe field does not show the exclamation mark. Note: When this custom control extension is added on the default page of work item, it's showing exclamation mark correctly. If I create one on other pages, it will not show exclamation mark
