Wrong info around browser.ui.interaction.preferences_paneSearch

Not sure whether it's meant this way. In the above link it's said to be a scalar, but actually a keyed-scalar in main (link)

This does seem to be the case for keyed scalars in general in the probe dictionary. So this bug is not limited to just this one keyed scalar.

It's almost definitely getting the type from the top-level type field, whereas keyed is buried deep in the details (root.history.release[0].details.keyed). Seems like it should be a straightforward fix to also check the latest details.

Fixed by #128.
