[Bug] Typing k in vocabulary search makes a word known

When I search for a word in vocabulary and write character “k” into search field all words currently displayed in vocabulary become known.

Same issue when typing in numbers.

Sorry to hear that. We will have it fixed.

Try to test even for “x”. I rather have not tried that.

This bug still exists. It is really annoying because the user might not notice it and make many lings known by accident.
