Refreshing ANY editor URL navigated to the management app's project overview
instead of reloading. Not related to spaces in paths — verified path-independent
by reproducing it on a fileless `-/pcbnew` route with no file path at all.
Mechanism, from probing the actual ordering rather than reading the code: the wx
port registers its unload handler via emscripten_set_beforeunload_callback,
which lands in the CAPTURE phase and so runs before any bubble-phase listener
regardless of registration order. It closes the top frame -> fires
wxAppTopWindowClosed -> the quit dispatcher -> location.assign(exitUrl), and
that navigation overrode the in-flight reload (the reload itself failed with
NS_ERROR_FAILURE).
The quit hook already latched off for our OWN navigations
(markDeliberateNavigation) and on pagehide — which the existing comment notes
fires too late, at commit time. Nothing covered a browser-INITIATED unload:
reload, Back, closing the tab. This adds that latch, in the capture phase so it
precedes emscripten's handler; a bubble-phase listener registered at module
scope was NOT enough, which the probe showed directly.
Tradeoff, documented at the call site: if a beforeunload prompt appears and the
user stays, the latch remains set and a later File->Quit won't self-navigate.
That is strictly better than a page that cannot be refreshed.
