Descriptive Problem Summary:

Embedded wingets work in javascript winsets. However, when you use a javascript winset in the browser, the id of the current browser element is inaccessible, and the parent window of the current browser element is also inaccessible. Performing embedded wingets on specific elements, like [[default.id]] within a javascript winset returns the expected values.

The winset interprets [[parent.id]] as a decorated element, rather than the browser element's parent, and any attempt to read the self-properties of the browser via [[property]] embedded wingets similarly returns an empty embedded value.
