Leaking WebGLRenderer and more when rerendering on iOS

[Jashpatel1]

I am using r3f for a 3d viewer web-app. When I try to navigate outside of the 3D-containing component and then navigate back into it (change of props) (in effect rerendering the ), It creates a new WebGL2 canvas everytime whose context is not being lost. After hitting a certain number of canvases, safari forces a reload and crashes the app. This issue is only reproduced on Safari and Chrome on iOS. On Android Chrome or web chrome it works fine. I have tried manually forcing the canvas to dispose:
gl.dispose() gl.forceContextLoss() gl = undefined
I have also disposed of all objects using dispose from react-three-fiber:
dispose(model.scene)

I have seen references to the same issue here: #514
