Bug 455312

SUMMARY
***
The Bezier curve tool does not behave as described in the manual, and also displays some erratic behavior. 
***


STEPS TO REPRODUCE
1. On a new document choose the Bezier Curve tool
2. Click on the canvas.
3. Click somewhere else in the canvas

OBSERVED RESULT
A thin black line that ends where the 2nd click was made, no handles of any kind

EXPECTED RESULT
According to the manual: "Krita will show a blue line with two handles when you add a control point. You can drag these handles to change the direction of the curve in that point."

SOFTWARE/OS VERSIONS
Windows: Windows 10 Pro, ver. 21H2
macOS: 
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 

ADDITIONAL INFORMATION
The tool sometimes changes behavior: If a 3rd click is done *exactly* where the 2nd click was made it presents red handles. Trying to use these handles results in a curve from the 1st point to the 2nd point and a straight line from the 2nd point to the red handle (still unusable due to extra straight line).
