[FIX] web: properly set parent when using mixins

The parentedMixin doesn't automatically set the parent, so when this mixin
is used, the parent must be set manually. This wasn't done at several places,
and thus those elements weren't destroyed with their actual parent.

In master, we should probably make the ParentedMixin set the parent itself.
