Remove X from the map

When you hold down a key to open up the map it shows allies that died and their icon (X) won’t go away. It’s something bothering me a lot. I use my map all the time and it helps me with positioning and knowing where the enemy is and where my team mate died. Around that information I can do a play and try to kill the enemy.
My suggestion is that the (X) on the map from your dead team mate goes away after 5 seconds or it becomes X with another color, not grey like they always are.
