**Short description of error**
`window_manager.progress_end()` does not refresh cursor, and it stays as black box until user moves cursor to a button or area border.
Here is how it looks, the cursor should refresh right after `progress_end` call, but it does not happen:

**Exact steps for others to reproduce the error**
# Open attached blend file: {F8715097}.
# Place mouse cursor inside Text Editor area.
# Run script using {key Alt P} shortcut.
* (//It won't work if you run it with button since button will refresh cursor after `progress_end` call.//)
# The cursor will refresh only after `window.cursor_set`.
