Glowing no longer works on fishing bobbers

Closely related to MC-307625.

In previous versions it was possible to make fishing bobbers glow like other entities by assigning Glowing to them. While this tag can still be assigned it no longer has any effect visually, which is wrong.

To reproduce this, set the following command in a repeating command block, then cast a fishing rod: /execute as @e[type=minecraft:fishing_bobber] run data merge entity @s {CustomName:"\"test\"",CustomNameVisible:1b,Glowing:1b}

Expected outcome would be a glowing bobber entity.

Actual outcome is a non-glowing bobber entity.
