NVDA can not read text in dropdown menu when the mouse hovers it, but it works when keyboard focuses on it

[eileencai]

Steps to reproduce:

1. run FortiClient 7.2.3.GA
2. use the mouse to expand the dropdown menu, hovers any option of the menu
3. NVDA reads "vpn name list 'ipsec-ems' expanded'" then keeps silent, when you hovers any option, it does not read the option any more

Actual behavior:

NVDA reads "vpn name list 'ipsec-ems' expanded'" then keeps silent, when you hovers any option, it does not read the option any more

Expected behavior:

NVDA is expected to read the option value when the mouse hovers it

@eileencai how is the css of those objects? You posted only a small snippet here, please provide a minimal test case, maybe a small landing page designed with Forticlient where we can test this. Otherwise it is really hard to investigate further.
