@gaspoweredpick I cannot test right now. Try disabling the vanilla data pack and see if you can reproduce this.
Fixed in macOS 10.13.3 (17D47)
Confirmed for 17w43a-17w45b.
Try updating your computer's graphics driver
Still in 1.9

After exit the GUI press 'A' again without CMD
Confirmed.

Code analysis
Please link to this comment in the description.
The following is based on the decompiled version of Minecraft 1.13.
In net.minecraft.client.gui.GuiListWorldSelectionEntry
It seems that whether the mouse is actually on the arrow is never checked.
Solution
In
net.minecraft.client.gui.GuiListWorldSelectionEntry
,net.minecraft.client.gui.ServerListEntryNormal
andnet.minecraft.client.resources.ResourcePackListEntryFound
, check if the entryisSelected
before rendering colored arrows.
