How to reproduce the issue

I'm building a custom cmdline using vim.ui_attach.

Through the API, we get enough information to show a fake cursor at the command prompt, but the original cursor also stays on the screen where it was before entering the cmdline.

See screenshot below.

Expected behavior

When implementing ext_cmdline, the cursor should be hidden between cmdline_show and cmdline_hide events.

Actual behavior

The cursor is still there
