The minecraft:explosion_resistance component for data-driven blocks is used to set a block's resistance to explosions. However, the value set isn't calculated in the same way as vanilla blocks. For example, a data-driven block with explosion resistance 6 is far more easily destroyed than a block of iron (which has explosion resistance 6).

Example add-on: [^MCPE-155973.mcaddon]

Steps to Reproduce

1. Download attached add-on
2. Add the behavior and resource packs to a new world
3. Obtain the data-driven block added through the add-on (/give @s mcpe:blast_resistant_block)
4. Destroy a structure made of the blast-resistant block with explosives, and another structure made of blocks of iron (both blocks have a blast resistance of 6)
5. Observe result

Observed Results

Nearly twice the amount of blocks are destroyed in the structure made of the blast-resistant block when compared to the structure made of the block of iron, despite the two blocks having the same blast resistance value.

Expected Results

Both structures should be destroyed at an equal level: in other words, an equal number of the blast-resistant block and the block of iron should be destroyed.
