fix: Fix popup list position display error

When the same signal is sent multiple times simultaneously in C++, QML may only receive the middle signal. The received height is not the latest, causing the display position to be offset.

Log: Fix list display issue
PMS: BUG-336777

fix: 修复弹出列表位置显示错误

在cpp中同时多次发送同一个信号的情况下，qml可能只收到了中间的那个信号，收到的高度不是最新的，导致显示位置出现了偏移
