Describe the bug

I have the "Show ligatures in terminal" setting disabled, yet ligatures still render when I type in the input field.

For exmaple, .. and --.

To reproduce

1. Disable Text > Appearance > "Show ligatures in terminal"
2. Type .. into the input field.

Expected behavior

Ligatures should not render while disabled.
For example, typing a period character immediately after another period should not change the rendering of the previous character.
