javascript - The menu in the upper right corner of the single-page application developed by vue disappears for no reason in WeChat

Question

The single-page application developed by vue disappears for no reason from the menu in the upper right corner of WeChat.
Normal entry will not disappear, but if the webpage jumps to a page other than a single page, and you press the return key to jump back to a single page, most of the single-page WeChat menu in the upper right corner will disappear

Answer 1

Is that non-single page restricting WeChat menu permissions?
Hide the menu interface in the upper right corner
