[MC-293615] Tooltip formatting of "Items x number" is inconsistent across different types of items

When hovering over a filled shulker box in your inventory (translation string container.shulkerBox.itemCount), the tooltip looks like this:

[^Screenshot From 2025-03-12 00-03-26.png]

…or written out for those not logged in…:

Shulker Box
Firework Rocket x3

However, in a firework (using the new translation string item.minecraft.firework_rocket.multiple_stars) it looks like this:

[^Screenshot From 2025-03-12 00-03-50.png]

…or written out for those not logged in…:

Firework Rocket
Flight Duration 1:
3 x Small Ball
  Red

There is a third newly added translation string, item.minecraft.crossbow.projectile.multiple, which looks like this:

Crossbow
Projectile: 3 x [Firework Rocket]

This bug report is about the difference in these translation strings.

Translation code	Translation string	Example	To reproduce
`container.shulkerBox.itemCount`	`%s x%s`	`Firework Rocket x3`	`/give @s shulker_box[container=[{slot:13,item:{count:3,id:"minecraft:firework_rocket"}}]]`
`item.minecraft.firework_rocket.multiple_stars`	`%s x %s`	`3 x Small Ball`	`/give @s firework_rocket[fireworks={explosions:[{shape:small_ball,colors:[11743532]},{shape:small_ball,colors:[11743532]},{shape:small_ball,colors:[11743532]}]}]`
`item.minecraft.crossbow.projectile.multiple`	`Projectile: %s x %s`	`3 x [Firework Rocket]`	`/give @s minecraft:crossbow[minecraft:charged_projectiles=[{id:'minecraft:firework_rocket'},{id:'minecraft:firework_rocket'},{id:'minecraft:firework_rocket'}]]`
