Broken mnemonics in localized strings

[Dr64h]

I'm getting broken translatable strings in hidden docks in the sidebar.

Example 1: Latin letters (en_US translation). Getting broken mnemonics in strings.

Example 2: Cyrillic letters (ru_RU translation). All strings looks fine.

A line in the code:

terminal_dock_widget->setTitle(tr("Terminal"));

My assumption is that the mnemonics that are added automatically are initially broken in the sidebar, and when the translation is loaded, a сlean string without mnemonics is loaded.
