Bug: Raster tiles request for a STAC item that overlaps with other items returns a mosaic with the overlapping items

[slesaad]

Description

The tiles returned by raster api for a STAC item returns a mosaic if the item overlaps with other items.

However, the preview returns the correct image.

Reproduction / Examples

Stack: GHG prod stack
Collection: emit-ch4plume-v1
Item: EMIT_L2B_CH4PLM_001_20240228T030250_002798

• tile

Expected behavior

• Tiles should return only the image for the relevant item id, not the mosaic with overlapping items
