* fix(app): keep a closing tab's canvas off the next document
Tab components read the editor through useEditorStore, which resolves
to whichever tab is active at each call. When a tab closed, the next
tab became active before the closing canvas finished, so the canvas
registered its renderers with that document and its cleanup removed
them from the wrong one. Every closed document's renderers, WebGL
canvases, and detached editor DOM stayed in the remaining tab: about
1,200 DOM nodes, 320 listeners, and 2.5 MB of heap per open and close
in a production build.
EditorWorkspace now provides its tab's store to app components as it
already did for the SDK's useEditor, and useEditorStore returns it
inside the tab. App-level menus, shortcuts, and services outside any
tab keep following the active tab. Over eight open and close cycles,
DOM nodes, listeners, and the remaining tab's renderers stay flat.
* fix(app): bind the workspace itself to its tab's store
Vue resolves an injection from the parent, so EditorWorkspace could not
inject the store it provides and its own template kept following the
active tab, reading the next document while its tab closed. It now
takes its tab's store directly.
* refactor(app): pass the workspace its tab as a prop
EditorWorkspace read the active tab once during setup and relied on
WorkspaceView keying it by tab to keep that choice. WorkspaceView now
passes the tab, the workspace uses its store directly, and provides it
to the components below, so the binding is explicit in the template.
* test: keep the light-page setup from leaving documents unsaved
CanvasHelper switches a fresh document to Figma's light page so canvas
specs draw on it in the dark theme. Setting the page color counts as an
edit, so every spec's document started unsaved, and closing a tab asked
to save changes nobody made: both tab-close specs hit that dialog. The
store now exposes markDocumentSaved, which reload and save already use,
and the helper takes the light page as the saved state.
* test: wait for a closing menu before opening the next one
A menu stays in the page while it animates out, and a click on a menubar
trigger then is lost, so menu specs failed depending on which tests ran
before them. They now open menus through one helper that waits for the
previous menu to go and for the named menu to appear.
* test: configure storage through the current settings form
Storage settings moved the connection fields behind the provider row
and save them with one Save button, so the workspace spec timed out
looking for an Endpoint field that was not shown.
