script: Manage <iframe>
sizes in Window
(#34643)
Manage `<iframe>` size updates in `Window`. In addition to removing duplicated code, this will allow setting `<iframe>` sizes synchronously on child `Pipeline`s of the same origin in the script process in a followup change. The goal is remove flakiness from `<iframe>` sizing. Signed-off-by: Martin Robinson <mrobinson@igalia.com>
