[vim/vim] CursorMoved autocmd is triggered after vim.options['eventignore'] = '' (Issue #19039)

[Yggdroot]

Yggdroot created an issue (vim/vim#19039)

Steps to reproduce

There is a file named test.vim in current directory:

autocmd CursorMoved * echom "CursorMoved"

function! Test()
python3 << EOF
saved_eventignore = vim.options['eventignore']
vim.options['eventignore'] = 'all'
vim.current.buffer[:] = ['aaa', 'bbb']
vim.options['eventignore'] = saved_eventignore
EOF
endfunction

1. vim --clean
2. :so test.vim
3. :call Test()

CursorMoved output is still generated.

Seems similar as #8641.

Expected behaviour

No output at all. This is the expected behavior of the code.

And Neovim doesn't have this BUG.

That is a duplicate of #8641
