Some distinctions between Latin and Cyrillic
Related letters (or, more accurately, related-looking letters) should not just be carbon copies of each other. Although the two alphabets are siblings, they've got distinct histories and distinct expectations for what constitutes 'normal' forms.
To be fairer; the norms issue applies only to the T, M, and K here. The other letter pairs are actually unrelated letters that simply look familiar to us Latinspeakers.
