Can't translate objects in the 2D scene view

I’m not sure if I accidentally pressed a random hotkey or not, but I am now unable to drag my objects around in the scene view. I can select them, but the translate gizmo doesn’t show up (the box with the arrows pointing along the x,y,z axis). When I try to move them around, it creates a new selection box.

I am able to drag objects if I switch to the 3D view, however. The translate icon returns, but disappears again when switching back to 2D.

You need to uncollapse the SpriteRenderer component.
