When a crash report is generated, the players' positions are listed but not the players' current dimension. If the crash reports includes other entities, the dimension is not listed for these either but the coordinates are.

A sample crash report is attached (which was also attached to MC-198373). In the "System details" section, a player list is included that only includes player name, world name, x, y and z. The dimension is missing which makes the coordinates ambiguous.
