Not 100% dropping blasted blocks when only 1 TNT explodes and explosion power over 1

I noticed that when only 1 TNT destroys blocks, dropping 100% of blasted blocks in Java edition. However, in bedrock edition, the component of  "minecraft:explode" contorl the explosion power ,for example:

      "minecraft:explode":

{         "fuse_length": 1.5,         "fuse_lit": true,         "power": 3,         "causes_fire": false,         "destroy_affected_by_griefing": true       }

,

 Can't dropping 100% of blasted blocks when the "power" is higher than "1".

I think it's a bug because explosion should not destroy drops when only 1 TNT explosed.
