As most people know, the icon when a snapshot version of Minecraft Java is launched has changed from a crafting table to a dirt block. However, the Minecraft Launcher doesn't seem to have updated this icon for the always-present 'Latest Snapshot' version.

Note : I'm just assuming it affects all versions, and do not have the means to check that. The only ones I know it affects for sure are the Windows Legacy launcher and the Windows 10/11 app.
