Reproduction steps

This issue seems to be specific to macOS; my testing shows that Windows is unaffected.

1. Type pinyin in Zed terminal to generate marked text.
2. Repeatedly press Backspace to delete the text.
3. The last character of the marked text remains stuck in the terminal.
4. Clear it by pressing Backspace once more, or by typing new characters to overwrite it.

Current vs. Expected behavior

Current behavior:

Expected behavior:

The last character of the marked text should be deleted normally.
