Does theia has own language package?

I download language package from version is 1.84.0 for theia 1.41.1. but it seem that something do not display correct
after installing chinese language pack extension, as you can see in editor menu, part of it still not display chinese language.
when I use theia 1.32.0 and langage package is 1.55.2, all display ok. after update to high version, not display correctly

@wss This was a bug that introduced a few versions ago but should have been fixed with this PR in the latest version of Theia (1.43.0).
