In my website, drop down menu in vertical menu is behaving abnormally.
1. When I hover on parent menu, sub menu suddenly appears and disappear.
2. When I click on parent menu, sub menu is shown, but when I take my mouse cursor on it, it takes jerk.
3. When I take my mouse cursor on right side of sub menu panel, it continuously jerks and appears then disappears and so on.
It is very disturbing experience. I have also recorded a video of it, which can be seen at https://www.loom.com/share/b90a21006fd540daaa5ac5e48bbdc09c?sid=939e30bd-7faa-4b90-afa2-639b51d6da73
