patch 9.1.1147: preview-window does not scroll correctly
Problem: preview-window does not scroll correctly
Solution: init firstline = 0 for a preview window
(Girish Palya)
The 'info' window, which appears during insert-mode completion to display
additional information, was not scrolling properly when using commands like:
win_execute(popup_findinfo(), "normal! \<PageDown>")
This issue made it impossible to navigate through info window contents using
keyboard-based scrolling.
The fix correctly updates the w_firstline value of the popup window,
ensuring
proper scrolling behavior. Mouse scrolling was already working as expected
and
remains unaffected.
