Cursor does not stop blinking after :FZF (Windows, Git Bash)

### Checklist

- [X] I have fzf 0.54.0 or later
- [X] I have searched through the existing issues

### Output of `:echo system(fzf#exec() .. ' --version')`

0.54.3 (af4917d)

### OS

- [ ] Linux
- [ ] macOS
- [X] Windows
- [ ] Etc.

### Problem / Steps to reproduce

Run :FZF and select a file. The cursor blinks when you search the :FZF pop-up, but does not stop after you select a file from the pop-up.
This was tested in Git Bash (which comes with Git for Windows).
git and fzf were install via scoop.

Reproduce the issue in Vim on Windows using Git Bash by running :FZF, searching the popup, and selecting a file. Start from the :FZF entry point and the fzf#exec() version check; done means the cursor stops blinking after the popup closes, without changing behavior on other platforms.
