The translations selection rect is drawn incorrectly on the multiline sequence view

Scenario:

1. Open "data/samples/FASTA/human_T1.fa".
2. Make sure the "Wrap sequence" option is switched on.
3. Select a part of the sequence. The selection should be on the several lines. The selection should start from a base with position not divisible by 3 (maybe, the one line length should be divisible by 3, check it).
4. The selection rectangle on the translations frames is slightly incorrect. It is especially visible, if the "Translate selection" translation mode it active. See the attached screenshot.
