If you have the icon, the backpack may be at a different height than you expect. You could use debug mode to peek through the floor if necessary. If it really is gone, you could use creative mode to give yourself the items you lost.

Also note that the icon appears in the location you have died. It's possible that the bag rolled down a hill, or was destroyed by the thing that killed you.

Well if it was completely immovable and indestructible, I suppose that could be bad, too, given the idea of a 100% destructible world. It would be better if the map icon moved with the backpack, but it’s probable that keeping the map updated all the time isn’t performant, or perhaps it was deemed to matter too infrequently. If it’s under the ground, that’s a bug, and steps to reproduce it consistently are needed to fix it.
