Short description of error
Leak when moving node with Alt. If you do it quickly, then the chances are higher. The longer this is done, the more leakage.

This is not related to #100958, it was fixed over 10 hours ago. But this leak is even in the debug build of the master at the time

Hi, thanks for the report. I've not been able to redo this (followed your first video).
Do you've exact way to replicate the memory leak? Tested in current master build:
8cb3b49e51469b9689bfa44b85349149e17699dc
I have been trying to achieve this for a long time. It seems to me that the main thing here is to connect the wrong node at the beginning and cancel it
In fact, if do one to one like the video, then it should work

By following the video exactly, I can get leaks in:

Sorry, it looks like it's even easier to repeat it

I didn't expect this. For fun, I decided to try it and it happened. It has happened at 2.79
