[BUG] List widgets with many objects per item flicker when hovered

[SixofClubsss]

Describe the bug
When hovered over a List item, the highlight may flicker. This seems to occur more often with Lists that are constructed with many objects, possible optimizations to be had in that regards.

Relevant Package/Repo
Relevant to dReams, issue extends into dApps.

To Reproduce
Steps to reproduce the behavior:

1. Connect and sync dReams
2. Go to a List widget (Duels and Holdero Lists with many items)
3. Hover mouse pointer over List item
4. Watch if highlight remains solid or begins to flicker

Expected behavior
Once hovered, the highlight should remain solid as long as the pointer remains on that item.

Additional context
Mod at time of report,
