            Bug ID: 236747
           Summary: Make input element UA shadow tree creation lazy
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

We currently delay InputType creation for parser inserted elements until just after the attributes have been set, so that we don't wastefully create an InputType and the UA shadow tree creation if a non-text type="" was specified on the tag.  We don't do anything similar for script inserted input elements.  We could make the InputType creation lazy, but most of the wasted time is due to the shadow tree creation.  I think we can make the shadow tree creation lazy.
