The events triggered by the default components used by the BeanEditor
can't be caught: those components are rendered from other pages, they
aren't part of your page hierarchy, so component events bubble up on
the other page hierarchy.
In addition, the client element ids are documented, but the component
ids are part of the implementation of BeanEditor or, more
specifically, the contributions to the BeanBlockSource service.
In other words, the TextField component that edits the backgroundURL
field is component core/PropertyEditBlocks:textField, so any events
would have to be caught by PropertyEditBlocks, not your class.
Further, the exact same component, configured differently each time,
will be used to edit every property in your for that's data type is
"text".
