Steps to reproduce

1. Create init file ('init-winscrolled-winwidth.vim' in this example') with the following contents:

let g:winscrolled_events = []
au WinScrolled * let g:winscrolled_events = g:winscrolled_events + [expand('<amatch>')]

2. Run vim -u init-winscrolled-winwidth.vim.
3. Create new window with vertical split (<C-w>v).
4. Switch back and forth with <C-w>l<C-w>h. This consumes WinScrolled events resulting from initial vertical split.
5. :echo g:winscrolled_events. It should show ['1001', '1000'].
6. :set winwidth=10000. Current window should occupy maximum width, i.e. it was resized.
7. Again switch windows back and forth. Each switch leads to resizing of current window to maximum width.
8. :echo g:winscrolled_events. It should show ['1001', '1000', '1001', '1000'].
9. And again switch back and forth. Each switch still resizes window.
10. :echo g:winscrolled_events. It now shows the same history as after previous echo, but it should have added two more window numbers.

Note: same applies to winheight and horizontal split.

Expected behaviour

WinScrolled event is activated after any window resize, including resulting from winwidth and winheight.
