Closing Steam with X now marks it hidden (state steamHidden). Before,
bar-only ended as soon as any window became active, so closing a docked
window afterwards let stock SteamVR fall back to Steam.
While hidden, the stock fallbacks go to the most recently active other
docked window with a tab, else bar-only:
- autoSwitchOverlayIfNeeded with no active frame;
- the dashboard mailbox's dashboard_overlay_destroyed handler (stock:
switchToHomeOverlay -> Steam);
- show/switch requests for Steam with reason "theater frame destroyed"
(key removed) or "SetDockLocation" (echo of X docking Steam: dropped).
Steam becoming the active frame (tab click, Steam menu pick,
SwitchToDashboardOverlay) ends hidden.
The hidden state replaces the rule that swallowed the first
ShowOverlay(main) from Steam after each dashboard open in bar-only (Steam
doesn't send one there; its only effect was eating a real Steam menu
pick). Version 7; state of versions 5/6 is taken over (bar-only implies
hidden), their fields are left for a rollback. Signatures: mailbox and
dashboard handler anchors, the ShowOverlay ones dropped.
Document the patch calling convention once in lib/default.nix; patch
headers say what, target, hook, state and contracts. Comments only, no
code changes.
steamFrame.dashboard.steamCloseButton.enable (default false) gives the
SteamVR dashboard's main Steam window a close button: it docks the window
back into the dashboard, then switches to the previously active window or,
with none, leaves just the dashboard bar. Bar-only survives dashboard
reopens and patch restarts (state in window.__sfuiSteamCloseState, taken
over from the earlier personal version 4 of this patch); the stock
"no active frame -> show Steam" paths are suppressed while it lasts.
MobX, the dock-location enum and the closing component class are found by
signature; check-only signatures cover the dashboard internals it uses.
