Steps to Reproduce:

1. Set "terminal.integrated.rendererType": "dom"
2. Open integrated terminal with bash session
3. Run for i in $(seq 1 30) ; do echo -n 0123456789 ; done
4. Observe missing digits at right-hand edge of terminal
5. Compare with default renderer, where all digits are visible, and characters are rendered with slightly narrower widths

With the default terminal renderer, this issue is not observed:

Does this issue occur when all extensions are disabled?: Yes
