A local menu will pop up, with unlocalized entries. See the 2nd screenshot. These menu items are UNO commands, and the labels are part of the configuration, which is read during startup (en-US), and don't change. Currently we cannot change configuration per view. Language switching, that works for other resources, does not work here. On the other hand, we rely on English UNO command labels when we do client side localization. The Javascript code in the browser expects English strings, and translates them locally to target language for main menu for example.

Confirmed.
We do not tunnel spellchecker and chart popup menus any more. Rather we build them client side with JS code. Localization uses the l10n framework client side. Fixed on master branches of core and online by Tamas Zolnai (multiple commits).
