Scripting

Priority: 2Necessary for shipping a final release

Severity: 3Workaround is possible

There is an attached project with a script, which creates 10 child objects and add Image component to them. Also there are OnEnable and OnDisable methods, which outputs an error message to the console. They both are called 10 times after pressing play. They are not called, except for initial OnEnable, if the line which adds Image component is commented.

Reproduction steps:

1. Open attached project
2. Press play
3. See the console output

Expected: 1 message in the console
Actual: 21 messages in the console

    From what I can tell, it also calls OnEnable and OnDisable on all children AND their parent canvas, and the canvas's parent in turn. Will add a Example project when I get a moment.
