Button hover highlights in the new Friends menu use the old blue tint instead of a white outline

The revamped Friends menu introduced in 26.4 snapshot 3 features a person-shaped icon button when hovering over a player’s head. This button, when it is itself hovered over, is given a blue tint.

This blue tint is reminiscent of how button hover highlights looked in game versions prior to 1.15 Pre-release 1, nearly 7 years ago, when they were changed to instead have a white outline. (a few legacy buttons have still never been updated, but are outside the scope of this issue)

Needless to say, it is highly unusual and inconsistent for a newly introduced button widget to use a style of hover highlight that was replaced so long ago. I would expect instead that the button, when highlighted, would be given a white outline, much like most buttons in the game do.
