Coordinates problem with -0 and looking at

In F3 debug menu, the player coordinates has -0, while the block ones doesn't. This makes a problem with "Looking at" string, which, in this case, tells that the block is in -1, while the player is in -0. This screw up the entire negative coordinates. Idk if it's intended, but I wanted to report it.

P.s: the bug I found is in 1.12.2, but the Jira doesn't let me change version to it. Some help?
