When creating an input element's UA shadow tree, we currently use a ChildChange::Source value that depends on whether the input element itself was parser- or script-inserted. But since UA shadow trees are not exposed to content, and we don't have any dependency on the extra work that inserting using ChildChange::Source::API does, we can use ChildChange::Source::Parser unconditionally. Local testing showed this scored a 0.1% Speedometer 2 improvement.
