Tellraw effect spread

/tellraw @a [\{"color":"red","text":"5"},"3","1"] results in red 531, not red 5 and normal 31

 

[BEFORE EDIT]

 

Run

    summon area_effect_cloud ~ ~ ~ {CustomName:"

{\"color\":\"red\",\"text\":\"2\"}

"}

    tellraw @a [

{"selector":"@e[type=area_effect_cloud]"}

,"3"]

 

Expected:

 

A red 2 and a default color 3, like what tellraw @a ["",

{"selector":"@e[type=area_effect_cloud]"}

,"3"] do

 

Actual:

 

Both 2 and 3 are red, and mouse hovering 3 show info about the aec
