PageRowGlobalToolBarUI: make breadcrumbLoader invisible when inactive
Otherwise the contents can show up after setting active: false
It fixes this issue on the Users KCM, where it switches from Titles
to Breadcrumb
style depending on available width, but both of them end up showing up when root.wideMode: true
:
This behavior was hidden before !420 (merged) because it turned down the opacity
in that case.
I only tested it on KCMs on desktop with no regressions found, but there are no layers, and the Users KCM is the only one using the dynamic change of header style.
