Found by minimising the app on the rig with a face selected: the whole screen goes black and the chip is still drawn on the bare desktop. A wxPopupWindow is override-redirect — the window manager does not own it — so it neither iconises with its frame nor stacks behind other applications. IsShownOnScreen does not catch this either: an iconised frame still counts as shown, which is why the guard added for the tab case sails straight past it. So the frame has to say so itself: ICONIZE and ACTIVATE, both routed through the same show_status_hud the page change already uses. Restoring is safe — a popup cannot take focus, so our own Show() cannot re-trigger either event — and restoring while some other page is up still leaves the chip down, because show_status_hud(true) goes through place_status_hud's IsShownOnScreen guard. Verified on both rigs: chip up, minimise -> screen black and empty, restore -> chip back with its text and the face still selected. Restore while on Prepare -> chip stays down. This is the fourth defect from the same root, so snaporca-lcq now asks the question these binds keep deferring: whether the line should be canvas content, like the view cube and the round view buttons, rather than a window that has to be told about every way a window can stop being visible. Fork parity unchanged: DesignCanvas.cpp 16.
