Subject: [PATCH] Register ToolTip attached properties correctly.

Was previously registering them with `Popup` as the owner, which was causing two properties with the same name to get registered, confusing XAML.

We should probably put in a check to make sure this doesn't happen, but this fixes the problem for now.

Fixes #1573
