Broken: 3.6

Short description of error
When i try to select all codirected edges, blender only selects few, despite even high threshold
Expected: select any edge, that is similar. (calculate module of dot-product for vector comparation)

I have this reesult

Exact steps for others to reproduce the error
Open the file, press Shift + G and select «Direction», Try to increase threshold

Thank you for the report.

In fact the Select Similar should search for edges pointing to the opposite direction too.
So confirming the issue.

Not able to confirm the fact of regression.

Code already tries to do this, see the following in edge_pos_direction_worldspace_get

/* Make sure we have a consistent direction that can be checked regardless of
   * the verts order of the edges. This spares us from storing dir and -dir in the tree_3d. */

Will check on this
