Current behavior 😯

ListItemSecondaryAction visibility does not change from hidden to visible on hover when implemented using CSS.

Other CSS rules like background color work perfectly fine and change on hover. But visibility does not switch from hidden to visible.

In case of switching from visible to hidden on hover, the ListItemSecondaryAction blinks on hover.

Expected behavior 🤔

ListItemSecondaryAction should be able to be hidden by default, then visible on hover. Or visible by default and hidden on hover.

Steps to reproduce 🕹

Here is a CodeSandbox that showcases this bug.

Context 🔦

A similar bug was reported in 2018, https://github.com/mui-org/material-ui/issues/10285. We used the suggested solution in our app and were happy with it. But the recent upgrade to V5 brought back this bug.

Research direction

Start by running the linked CodeSandbox and inspecting demo.tsx, which reproduces the ListItemSecondaryAction hover behavior. Compare the visibility and background-color rules, then trace the component's rendered styles in the Material UI source. Done means visibility reliably changes in both hover directions without blinking, with regression coverage added if the relevant test location is identified.
