1x1 texture from drawRect

I want to draw some lines and rects, usual strategy for doing this in other game engines is using a 1x1 texture in a scaled and tinted sprite, but in PixiJS I found a strange problem with this.

Texture from drawRect(0,0,1,1) doesn't work, while drawRect(0,0,2,2) (or 2x1, 1x2, or 2x2 with frame = new Rectangle(0,0,1,1)) works.
