Defer opening the rename dialog past the context menu's close

Opening the dialog synchronously from the menu item's onSelect races
Radix's menu close/focus-restore against the dialog's focus lock and
can freeze the webview (observed as an app crash on rename). Deferring
one tick lets the menu fully close first.
