Bug: icon tooltips are far off their button after a resize #41

Problem

• After the window is resized (maximized, moved to another screen, resized with the mouse), the tooltips of the icon buttons appear far below their button; at the top of the window they lie outside it and are not seen
• Expected: the tooltip right below (or beside) its button, as before the resize
• Seen on main (0.3.0, 798a52a) with Makie 0.24.16, GLMakie 0.13.16, Windows 11

using BeamletOptics, BeamletOpticsGUI, GLMakie
gui = live_view(System(); layout = :app, size = (1600, 900))
screen = display(gui.fig)
resize!(screen, 1600, 700)   # or resize the window with the mouse
# rest the mouse on the button "Trace" at the top left: "Trace (t)" shows next to the object tree

Tasks

• After a resize, the tooltips of the toolbar, the cards and the catalog appear at their button
• A tooltip at the top of the window stays inside the window

Notes

• Cause in Makie 0.24: a tooltip plotted into a child scene is placed with the window size from before the resize; one in the root scene is correct (upstream issue drafted for MakieOrg/Makie.jl)
• The tooltip of the object tree lives in the root scene and is not affected
• Fix on branch fix/tooltip-resize
