Some transparent items make transparent blocks and beacon beams not render behind them

MC-9553 was mainly fixed, but a part of it (visible in a screenshot) still applies. As asked for in MC-9553, I'm creating a new report for it: If the drop (item entity) of ice, stained glass or some other transparent blocks are in front of a Nether portal, the portal does not render behind it and instead the blocks behind the portal are visible through the item entity. This does not affect drops of e.g. regular glass. It also affects water and beacon beams (in place of the Nether portal blocks) and held items in third person mode (in place of the drop).
