Of course, the version isn't the most critical issue, because this phenomenon has persisted for at least 2-3 years, across multiple versions of the relevant software, and it's always been like this.
当然，版本不是最关键的问题，因为这个现象至少2-3年了，历经相关软件的多个版本，都是如此。

Personally, I think it's an issue with Edge's adaptation to Mac.

This phenomenon doesn't occur every time, but it happens fairly frequently — by my rough estimate, about 70% of the time.
这个现象不是每一次都出现，但是出现的次数是较为频繁，凭感觉估计是70%。
