Objectives not working in hoverEvent

Description
When an objective is attempted to be displayed via score:{} in a hoverEvent:{}, it is not displayed. (Both tellraw and Written Books) It is however displayed outside a hoverEvent:{}.

How to Duplicate

Run this in the command line:

/scoreboard objectives add test dummy

Then run this in the command line:

/scoreboard players set @a test 1

Then place down command block down and run via the command block

/give @a minecraft:written_book 1 0
 
{
	title:"Book",
	author:"",
	pages:["{
		text:\"\",
		extra:[{
			text:\"Objective:\",
			color:red
		},{
			score:{
				name:*,
				objective:\"test\"
			},
			color:blue
		},{
			text:\"  \"
		},{
			text:\"Hover Here\",
			color:green,
			hoverEvent:{
				action:show_text,
				value:[{
					text:\"Objective:\",
					color:red
				},{
					score:{
						name:*,
						objective:\"test\"
					},
					color:blue
				}]
			}
		}]
	}"]
}

As you can see the score is displayed at first (in the blue), but once it is within a hoverEvent:{} it no longer displays.
