Fix artifacts in freehand selection tool in polygonal mode
Fix the line artifacts stuck on the canvas when using the freehand selection tool in polygonal mode (ctrl shortcut). These lines would generate just from moving your mouse around while having the polygonal mode active and would stick around until you moused over them again.
Test Plan
- select the freehand selection tool
- press ctrl to activate polygonal mode
- Move and click around the canvas (there should be no "left over" lines stuck on the canvas)
