RFR: 8316423: [linux] Secondary Stage does not respect Scene's dimensions when shown

Thu Sep 28 00:37:57 UTC 2023

It looks like a condition between calls from `set_visible` to `request_focus`. When `request_focus` is called, the window is not yet mapped (map is requested on `set_visible`). 

200x200 is the default gtk window size if none is specified. Since the window is presented at the requested size and then changes to 200x200 I would guess the size request on `gtk_window_present` (which is called on `request_focus`) is being queued and released later. But I'm not really sure.
