1739335 - Always highlight hovered frame in iframe picker

Status: ASSIGNED

Description

[Nicolas Chevobbe [:nchevobbe]]

Bug 1395367 added the ability to highlight a frame document when the item was hovered in the iframe picker.
Due to technical limitation, this highlighting is done only when the top level target is selected (See https://bugzilla.mozilla.org/show_bug.cgi?id=1395367#c14).
With the work around fission and EFT, we might not have such limitation anymore and can probably remove it

also, we don't have a test for this feature, so it would probably be a good time to add one

About bug 1395367 comment 14, this is a bit outdated. I wrote that when highlighters weren't fission compatible and we weren't having proper target support. Today, we could probably do something client side, using top level target front, instead of focused target front.
