Macro: adjacent three-digit numbers above nucleotides in the Sequence mode merge due to lack of space between them

**Steps to Reproduce**
1. Launch “Ketcher” and switch to the Macro mode
2. Switch to the fullscreen mode
3. Draw more than 102 nucleotides connected between them by bonds on the canvas
4. Go to the Sequence mode
5. Hover on the last nucleotide
6. Verify how adjacent three-digit numbers are displayed

**Actual behavior**
Adjacent three-digit numbers above nucleotides in the Sequence mode merge due to lack of space between them

**Expected behavior**
There must be a space between adjacent three-digit numbers above nucleotides in the Sequence mode
