Ores no longer drop experience when blown up

The Bug

When blowing up nether gold ore, coal ore, redstone ore, lapis ore, nether quartz ore, diamond ore, and emerald ore, it no longer drops experience. These ores dropped experience in 1.14.4 when blown up by any means (regardless of whether it's done by the player).

Steps to Reproduce

• Summon a large cube of diamond ores.

  /fill ~1 ~ ~1 ~9 ~5 ~9 minecraft:diamond_ore
  

• Place some TNT on top of the large cube and ignite it.
• Take note as to whether or not the ores drop experience orbs upon being destroyed by explosions.

Observed Behavior

Ores no longer drop experience orbs when destroyed by explosions.

Expected Behavior

Ores would drop experience orbs when destroyed by explosions, just like they did in 1.14.4.
