The Gravestone Mod is intended to keep your items safe. if it can be just deleted by the dragon, your items are not safe (even if they just pop out of the gravestone, that has a 5 minute timer)
Describe the solution you'd like
Quite simple, add gravestone:gravestone to the block tags of minecraft:dragon_immune.
Describe alternatives you've considered
I have made a datapack that fixes this problem by adding it to the minecraft:dragon_immune tag
