// Deliberately not preloading DataGrid here for every tab: evaluating that

// unconditionally shortly after any tab mounted, including source-only
// tabs (e.g. viewing a large object's DDL) that never need a grid. That
// turned a "warm the cache" optimization into a multi-second main-thread
// freeze right when the user was trying to read the newly-opened tab (see
// issue #8103). The watcher below still preloads it eagerly for tabs that
// actually need one.
