Flickering border on inactive window with window rule

[JoMaZu787]

When I add the following window rule to my hyprland config:
windowrule = bordercolor rgba(ff0000ff) rgba(00ff00ff) 90deg rgba(00ff00ff) rgba(ff0000ff) 90deg, tag:waypipe
and tag a window with the waypipe tag from the rule, the window's border is a gradient from red to green, top to bottom when it is focused (as expected) but when I move the mouse to another window, the border stays that color for about a second, and then turns gray like the borders of all other inactive windows, instead of fading to a reverse version of the first gradient as specified in the window rule.

In addition, moving the mouse between two other windows, or sometimes just within a single window causes the inactive window's border to flicker between the default gray and a light blue color.
