Program unresponsive to the first click after startup on a Windows 7 32-bit touchscreen device

In my software developed for a Windows 7 32-bit touchscreen computer, I noticed that the program's window does not respond to the first click after startup, despite being in focus. However, if I click again, it responds correctly, and all subsequent clicks work fine. The webview within the program functions properly before the first click, and the animations display correctly. I suspect it is an issue with the webview window not receiving focus, but I am unsure how to resolve it.

Target device:
Windows 7 professional 32 bit
Webview 109

Detail:
target i686-pc-windows-msvc

I enabled these four features in tauri.conf.json

"fullscreen": false,
"resizable": false,
"focus": true,
"alwaysOnTop": true
