patch 9.1.2142: MS-Windows: mouse scroll events not handled for popups

Problem:  MS-Windows: mouse scroll events not handled for popups
Solution: Do not return early (Mao-Yining)

Ensure mouse wheel events on popup windows are properly processed by
sending the corresponding key messages. Previously, early returns
prevented normal event flow, causing popup windows to ignore scroll
input.

fixes:  #19353
closes: #19369
