Updating gradient regurarly increases amount of node elements and overloads the page

[iamisti]

Describe the bug
I have a usecase when i need to update the gradient on the svg path multiple times.
Unfortunately every time I call the render method, it doesn't override the previous gradient node, but it creates new ones.
This becomes a problem after some time, when I end up 5k node elements, which is very bad for performance.

To Reproduce
Steps to reproduce the behavior:

1. Add gradient to an svg path
2. use .render method to render gradients
3. do it multiple times
4. check performance monitor in chrome and you'll see that the node count is going up

Expected behavior
I'd expect to have a cleanup process before the gradient renders

Did you find any way to fix this?
