An issue with Command Editor and Ctrl shortcuts

If I've selected non-English input language (non-latin keyboard layout) and then start Opus, Ctrl+C, Ctrl+V and other keyboard shortcuts don't work in Command Editor dialog:

But if I've selected English input language and then run Opus, Ctrl shortcuts work fine in the dialog (regardless of selected input language).

Opus 12.6

Which one? (So we can try ourselves.)

Russian lang

The problem still persists in DOpus 12.29
Is there a chance it will be fixed?
