Short description of error


Symmetrize operator automatically disconnects bone parenting for "Bone.L" if "Bone.R" was connected to a non-mirror-bone, for example "Bone_root". I assume its intended to force the Bone to the other side.
But in a case where the parent bones end / root of the connected bone is exactly at 0 on the X-axes, it might be relevant to preserve the connection, as you can see in the picture.

Exact steps for others to reproduce the error
